Looking really good Willie! Keep going with this man
I see a few things proportionally:
his head in profile looks a bit large, and I think you could raise his chin(rotate head)
His chest feels a bit in line with the rest of the torso, I think maybe adjusting it a little bit to create a plane break in the model would be helpful.
Shoulders arent as pronounced at the cap, the drawing is more volumous
Some indication of the latissimus area in the back view would give him more shape imo
Upper leg in the side view could use a little more curvature, right now it looks very straight.
