Nice work! I do like the Vallejo line for figure painting.

Nice mate, figure painting and especially flesh painting is just a matter of practice. I used to paint flesh areas with oils and had a pretty good method but then moved to acrylics and had to learn a new set of methods to get results I was happy with. The trick with acrylics is to build the effects up over a few or a lot of layers depending on what you want to achieve.
