I think the main thing that is throwing me off with this is that the body doesn't flow vertically. Check out the middle red line I put over the figure. The chest needs to be placed in relation to the abs and then slopes down to the knee where it arcs back forward. In greek they called this side viewing and counterposing "Contrapposto." It can also be directed over to the art term of the natural "S-Curve." The counterposing is done naturally by the body to offset gravity.

I would also slide the shoulders back because they are positioned in the back third of the torso and not directly center. Other than that it looks really good for detail.
