Very cool protocol droid CHEWIE. It does look like the type of droid that I would imagine the bug guy would have.
I am going to have to agree about the Clone's shoulder pads - they don't really fit the figure(a little too bulky, as Diddly put it). Also, I would try to do something with the helmet to change it up a bit. Maybe throw on a tweaked AT-TE Tank Gunner's upper helmet piece or use a repainted TIE Pilot helmet (that's something that I plan on doing soon, when I have time

). I think that would be pretty cool. I like the idea of the shoulder pads, but I think Kevin might be on to something about painting them a different color.
That Imperial Officer is great! What legs did you use? I like the BoShek head, he definitely looks like an Imperial Officer from around the time of ANH. Did you cut the Imperial hat off of Ozzel or is that a cast?
