EDIT - Just to make sure, you guys know that I am sculpting on a cast helmet with new details and not 100% from scratch? Just want to make sure everyone knew that. I use the base cast (though usually highly sanded down with a dremel) The Galactic Marine uses a sanded down Bakara head as the base frame work, the Clone Engineer uses a sanded  down stormtrooper cast as a base, the Parjai Airborne helmet uses an AT-RT driver helmet (mainly for "mouth" details) and the Artillery/Demolitions Clone uses a Cody helmet cast. (Though far more of the Cody cast is visible with that sculpt as I wanted those details to show with my sculpts as add ons.) In most cases that base cast as framework is there for something non-mushy for the sculpy to stick to and to help keep my sculpt to scale with other existing clone/stormtrooper helmets.

I did 3d modeling for a game (star trek armada modding) for six years prior to starting this hobby. Though working with clay and 3d modeling on a computer are two different worlds, I know 3d modeling helped me actually think in 3d terms. In reflection of my art from prior to 3d modeling was pretty much limited to a 2d perspective. Meaning I was ok at drawing, but suffered where shading and lighting was concerned. Now I can in my minds eye, see an object rotating at various angles with detail but six years ago my ability to envision such thing was very limited.

I kinda scorched my Clone Engineer helmet in the oven. It looks darker but should still come out just fine once I get it molded and cast. I am waiting till I have about six  helmets sculpted before I start making molds. So about two more to go.

By the way! Cool trick I found for those who do custom Casting. If you get parts that have small bubble holes in the cast part, there is hope! If you have some Sculpey, take a peice of it and lightly rub it over the areas with bubble holes lightly at different angles. This will help fill in the holes. I have to really look hard to find the areas that had bubble holes now! Next step, boil the cast peice to make sure the sculpy hardens.

The last helmet is still being worked on. I need to fix a few things and sand down some of the uneven parts of the "antenna". I used part of a paperclip inside the sculpy to give support for the antenna.
Ugh... just woke up and need coffee desperately.. I appologize if this last post did not make too much sense...

Considering some jokes my girlfriend has made about my clonetrooper figures, she will definitely get a kick out of that picture! hehe

Those clones are awesome! I always wondered what customs could come from the AT-RT body. Now I know...really great ones! I love the addons on the Urban Shocktrooper. Did you sculpt those additions?

Looks great!
The brown and green go together well and the skirt adds a nice touch.

WEG star wars had so much cool stuff. I still got alot of the books.
These figures inspired me to do some searching at my local Wal-Mart today, and much to my suprise the 21C figures. Seeing what you have done with them shows that they would make excellent customs fodder.
What display diarama is the plastic rock from? The old Sandcrawler Diarama?

Thanks BrentS!
I am now starting on a Clone Engineer helmet, from Star Wars Battlefront2. I will try to post some pics later on this evening (well, evening Pacific time that is...) on that project.
What follows is some of my previous stuff. (The playdoe sculpting attempts have been removed... a bit ashamed of them now, but it was only sculpting media I had to work with up until couple weeks ago...)

What follows is a cut and paste of some of what I posted over at YakFace recently. This is my older stuff, but since I dont have alot of finished (or started enough to take pics of...) I figured I would show these. I eventually plan on redoing the "Bakara" style Utapau troopers with fully articulated body and possibly some armor changes and slight helmet alterations as well.
My Galactic Marine peices I have been working on...
Helmet and pauldron. I am reworking the pauldron soon. I used a cast and sanded down Commander Bakara helmet as a base for this helmet.








The boots for the Galactic Marine... (used sanded down snowtrooper leg casts as the bast. This is still a work in progress)
I figured my old snowtrooper repaint could help display the sculpted legs.













My first custom attempts! Simple repaints.












UPDATE!!!
Well, wanted to give the Clone Engineer a shot for some time. I finaly felt up to it today. Did alot of game pausing with my Xbox today to try to get some different angles. I pretty much just need to add some detail to the back sides of the helmet.
Let me know what you think.

I normally post primarily over at The Jawa, but I need to branch out a bit more. I started customizing arround the end of may this year and just started sculpting about a month ago.

Well today I wanted to give a fourth attempt at this helmet...
I used a cast AT-RT driver helmet with some dremel sanding down on some areas as a base to sculpt on. Partly cause I wanted the front "mouth" area to have some detail in it, and the AT-RT driver helmet had the middle/back detail I wanted included on the helmet (that I did not feel I was ready to sculpt with appropriate detail yet.)
Well here we go with the pics (sorry about all the fingers in pics, needed to hold sculpt support in place.)





next to the one that ended up too big, as comparison...


After I mold and cast this, I am going to modify a cast one so that I can have a Commander Keller helmet as well. (Sadly I have never read the comic he was in, much less know the name of it, but I see pics from it all over the place.)

I will post a few other things I have done so far in near future...

Darn... I think it would have be really cool to have a X-tra crispy Beru and Lars Action(?) Figures. I am only half joking...I would buy a few of each just for humor value alone! The same would apply if they had made the Funeral Padme Action(?) Figure...

We need to do full customs of all figures on that joke screen, complete with package. As an addition to standard "Saga" formatting, we could add in a bold exploding image "Best Wave Ever!"
A blaster charred Aaya Secura corpse would have made that collection even better!

Yes it was a bad joke on Hasbro's part, but I seriously would have bought the entire wave of figures. Maybe they could make it an Entertainment Earth Exclusive collection...hehe
