Wanted Cowboy Concept 3D - Critique appreciated

Hello there.
This is my first post here, and I was looking for a critique on this character I am working on for school. It is based on a concept I came up with myself. Appreciate anyone who could give some suggestions on how to improve :smile:

Seems I can only put one image as a new user so hopefully it does justice on the model.

if he is a cowboy he should have those spurs(i think thats what they are called) on the back of his boots
