Gray - A LowPoly Game Character

Its the first time I modelled a lowPolyHuman by myself, so, here is it:

I call him Gray. I want to use him in my Game-Project.

I made a few more Renders, but cant Post them, because of the Forum-Rules…
I will post them in new Post, if you want.

So, what do you think of this?
What could I do better?

I like it. The purple hair really goes good with the gray. One thing I see is that around the shoulders the mesh looks indented in an awkward way. otherwise, good job!

feet look smallish.
