Arknights - Flamebringer

I don't know how to draw a man. I never complete a 2D drawing about man as I always do not feel satisfied about my drawing. It is easier to draw a girl for me.

This is the first time I made a 3D man figurine. I think the most difficult thing are muscle and face. These are totally different from a girl. I really hope there is a muscular man doing the same pose and let me take some photos as reference Haha^^.
