Don't worry. I'm doing Stormtroopers (plastic boys), Rebels (egg heads), Clone troopers (also plastic boys), and Droids (brainless slaves). Not very creative on the names, eh? *made them all from playing BF II* I might also do Jedi, if I can make a lightsaber.
Now, how to draw some of these? Rebels are easy...just draw one of their helmets on a Dragon and possibly a vest. Stormtroopers and Clone Troopers are harder. Their helmets are different and much more difficult. It'll take longer for them. I might give them shoulder plates too. Droids are harder. You'll be seeing red-eyed Dragons here. Along with metal arms (All will be based on the Super Battle Droids). Hey, those might end up the coolest ones...
As for Jedi, let me see if I can do a lightsaber. If I can, awesome. If not, oh well.
