hey Minstrel - this is coming along great - I like the hands a lot.

Aside from the overall symmetry of the muscles, my main crit would be that in the side view the whole thing looks a little vertical. Usually the different parts of the body will sit at a opposing angles. So the ribcage will lean back on its axis and the pelvis will lean forward. Similarly, the same thing happens with the leg. At the moment everything looks a little straight up and down which is making him look a little stiff.
