Model looks fine, I would rather have it have more color though.
model looks suspiciously ripped off some other game; its pretty dang high poly and has some parts that look like should be textures but arentits okay if it is ripped - just dont take credit for stuff you didnt make.
I'll be honest I made the model.
what did you model this in?
Select all of the faces, go to groups and make sure auto smooth is checked. Go to vertex > unwield and uncheck box, then weld them back together.It will make the model look a bit nicer.
