The designs with wings and feathers are seem far too similar to Tomohawk, (with the exception of defno's awesome switch). I kinda wish I was a decent enough artist to do prevo justice, but in general I think designs that show detail as to whats under that giant faux bird cloak when its removed are really cool.
@Energy storm: I don't know if you're still working on it, but I really love that prevo sketch you have on the first page!
@Paintseagull: I think the new pose looks awesome~! Great change.
EDIT: Mos-Quitoxe's is awesome too!! (By the way, thats not what I meant by lacking feathers. I just prefer if the prevo looks less bird-like I think XP.
