I'm getting started with this just now, and I wanted to say your topology is really great.  I think I'd do things slightly differently at the thigh and the abdomen to follow the major muscles there but everywhere else is truly excellent, particularly the deltoid-to-pectoral polys.  Shape-wise this is very refreshing and normal.

I have one other very specific bit of feedback that I'll mail you as it's rather indelicate ;)
