ok, so I now see a problem with where the legs attach to the body. It was not apparent until I looked more closely (call it "blinking twice"). Thanks for your help!
It is great to see there is somebody out there; thanks for your reply! So are you saying that modeling should be done concurrently with getting the gesture? Is modeling based on the lighting or on an intuitive understanding of the form? Sometimes I see a lot of latitudinal lines in quick sketches; this isn't what you mean, is it? I might go back to charcoal; that might help.
