More wonderful work, Chewie! I have commented elsewhere on the mystery hunter, Cmdr. Kraist, and Nommel, so here goes with some of the things from earlier on, upon which I haven't commented yet:
Quinlan Vos: Softgoods hair! Hooray!

Very ambitious, and it turned out great. (How did you get it on his head, incidentally? And did you spray seal it afterwards? It looks that way.) Yes, as Phruby points out, he does have that sort of Bob Marley look, but in a determined, Jedi sort of way.
Female Wookiee Peasant: Dath Delicious, I wonder if it's the eyes & teeth that don't seem right to you? They do seem a bit too white, almost "deer-in-the-headlights"-ish. Maybe if they were more off-white or a light tan? Still, I like the concept for the custom, and it's definitely a very creative one that one does not see every day.
Darth Plagueis the Wise: Great use of the imagination! I think it's neat that you made him, especially with no reference pictures about, but that's part of the fun, of course. Definitely very very creepy, in a good way, and consistent with what we know about the character. I have a totally different mental picture of the character, whom maybe I'll customize some day... hey, come to think of it, Plagueis (or characters without reference pics in general) would make a really cool Casting Call or Customizers' Challenge, no?

Outer Rim Pilot: I like how svelte he is (and I know why he's svelte), and I LOVE that he's basically wearing jeans.

Great transformation of that Naboo helmet (or I think that's what it is)!
Always enjoy seeing your work very much, even if it
does take me a while to comment sometimes. It's just that I want to give it the attention & time it deserves! Happy customizing, and I look forward to more, as always.
