Id say the feet and legs are good, but the thighs should be more round at the top to give it them that round 3 dimensional shape. The only thing that stood out noticeably is the placement of the belly button, it should be moved up one more spot in the abs, otherwise its really good. Hope i helped.
They were round on the straight lineart but I guess the towel is kinda hiding it. Hopefully I can fix that if I ever get to the shading stage. Gah... bellybuttons!
