Dodo ineptus

Thought I would try to make some low poly animal and found this model, I started it about two years ago when I got venom’s lab 2, but stopped because I couldn’t get the wings done and because of the feathers (originaly it was ment high poly and as realistic as possible). So I turned the subdivision surface off, cleaned the whole model up and remade the wings (low poly weren’t much of a problem) and this is the result:

I don’t have much experience with texturing and there isn’t any reference. If anyone has any idea how to improve (textures, generaly, anything), please let me know.
Please excuse any mistakes, english isn’t my mother language.
