This is not bad at all! Just the right leg, its connection to the torso looks a bit odd to me. I think maybe emphasizing the torsion of the torso would help with that. Adding a couple "folds" to the skin in that area could do that. Of course, clothing would solve the issue 100%, but there's a reason why we work with nude models, right?
Thank you for your critique of my picture. The model is from the Line-of-Action provided selections. I do not remember it I must admit. I do know there was no fold of skin to add. To draw/paint clothed figures, you need a really good knowledge of human anatomy - muscle & bone structure. In the nude figure, the evidence is there for the artist to see. You are correct.
