I think your nudes are progressing pretty nicely! But the clothed piece in this last page needs a little work. At first sight it seems like the upper arm rolls like that but there are actual pipe folds and zig zag folds in there. But I'm digging what your doing with the shading on it. I personally have not colored much in PS. So props to you.
Oh and the first and second page have some really great stuff in there!!!!
