While we're gettin' all anatomical and such, the vastus intermedius muscle is the one that doesn't look anatomically correct at all to me. Generally the vastus intermedius, vastus lateralis and vastus medialis all look too pronounced and a bit mislocated to be anatomically correct.

Just a bit of smoothing would probably fix that on the front of the thigh. It all looks so good that it's not worth having anything anatomically off.
