For that I might need you to tell me what you worked on exactly on those pictures, i cant tell whats different from original, well maybe except the fact that now its animated. :P
no worry, well expression looks fine to me honestly they match the situation so its really great, well done! Cant really tell in detail tho because its a bit small so I cant tell if there is something off with your photoshop but it looks fine to me from what I can see by folding my eyes very hard. x)
