crim package is pretty big, in order to use him with the clothes on I recommend shrinking it or making a copy of the body with it shrunk or the polygons hidden

Pieces with no thickness such as the dress, hair bangs, etc will look better if backface culling is off

Floating geometry like the eyes and eyebrows will give a better anime effect if they are set to not cast shadows, or the eyesocket to not receive them (the eyesocket is attached, you might consider unwelding it if it suits you better for animation or asigning shaders). Or use a flat light toon shader. 

I wasn't sure about the wings design, you might want to erase the brown outline on the contour by painting it white in the textures
