Hello. Pretty solid start to the piece, but I have to ask, what is the background of this character? His muscle bulk is enormous; I'm having trouble figuring out what his lifestyle could possibly be to account for it (besides, you know, Mr Universe).
The muscles are too segmented, which disrupts the movement and gesture of the figure:
Keep in mind the compound-form the muscles create when combined together.
I think you can omit the outlines on the lit-sides of the form, which I ended up with when cutting down the bulk on his right shoulder. Also his feet seem huge.
