I'd suggest getting rid of the neck; Ambipom doesn't have one to speak of... also the original positioning of the arms made ambipom look beefier, they're held against the body.I think the ambiray seems a bit... small proportionatly. I'm not sure what it is, but it looks really thin. Most of the other ones look nice, especially the genios and blastkrow.
ahahahaha this is awesome. mind if I avy it?
