Sorry my english isn't better. I think the second sketch has a problem with the front leg, For all I see dynamic and fluid line in the shapes and the figure.
Excellent work on your nude female figures, JBLEE, but I've got one small request: Why don't you try to think about and feel, your way to the overall proportions of the human forms, pretty please? The reason why is because, you'll get much better at the overall relationships of the human forms fairly quickly, well, and reliably. Hope and pray that it'll work out for you.
