I was thinking the same thing about the last dude. I see a lot of corpse parts there from an AOD figure (I've yet to get any though... I never get to a mall to look

).
The robes on the corpse looking dude are familiar... The familiarity makes me think maybe switching up the paintjob on it is a good idea. What's the character to be exactly though, a Senator type guy (just some random, unattractive species) or a Sith like Dime's mentioned? He looks eviil for sure, but so do many species it seems.
On the Wookie, you did a great paintjob CHEWIE, and he's very different to the Wookie Warrior basic figure... I dig that. Not wild about a crude axe as his weapon but that's just my view of Wookies as "something more" than other species. I could see a more high-tech axe or something though... Or, a warhammer. Warhammer's sheer brutality would be a neat weapon that I'd dig seeing in a Wookie's hands. Something that their physical strength would "back up"... Vague idea of a reaplacement, I know.
I'd outfit him with an extra bowcaster too though... Sucks going into a gunfight with a "knife" so-to-speak so I'd give him even a POTF2 Chewie's bowcaster iwth a sling over his back or some such. Just that extra umph for ranged battle.
You definitely painted him up much nicer than Hasbro's. Even the armor looks like you did a bit of work there too.
On Jar Jar, I think it's a shame we have yet to get a GOOD Senator Jar Jar from E2 actually. While not a pivotal character exactly, he's also not the bumbling idiot he was in E1 and was tolerable. He'd be cool as a neutral Senator figure some day, and the same can be said for your version... I'mc urious though if he's based on an E3 costume you've seen or just your own design of what he may look like in E3? I recognize at least the cloak, and I think it looks great... I like seeing his ears "back" and sort of out of the way... More dignified for some odd reason.
My favorite figure then is easily the Max Rebo guy... Nice use of parts, and it's neat seeing a species we've really only seen once actually out and about as a different character... That they're not relegated to sitting behind a piano!
The parts work well too, pulling off the squat, bulky body while covering him up quite well with clothes. That looks really cool, and I'd dig seeing more figures like that out of people. This is one of the neater customs in a while I think. Again on the colors though, I think I'd have gone with something different as that looks very close to the base colors... Kind of muted shirt with a bright tunic.
The only other thing, and I just notice it looking at him more... The arms seem "long". I'd shorten them somewhat, as I believe the species' arms are not that long whereas Pote's got arm length like a human does. Minor, but it caught my eye sort of. I could be wrong too though, as I don't have the Max figure to look at or a picture of him in the film... He seems squatter in the arms and body though to me.
All in all, great round-up of figures CHEWIE, nice work. You should take them over to FFURG to get some input I think... Lots of voices to add to it there and I'll re-add mine as well of course.
