I learned a couple things from this exercise:
1) I should use gradients and selections more often, especially for establishing large shapes
2) I should not place my trash can next to my desk
3) Some elements are not ideal, they look slapped on, such as the tattoos, they are too saturated on the man's arms/legs. It doesn't look attached to the skin, or subcutaneously but like stickers not receiving light correctly.
4) Creating a male & female costume design at the same time helps me from getting tied down to details too quickly, because I want to jump over the other one to match. I can hear Feng Zhu's voice in the back of my head telling me the benefits of working on more than one file simultaneously.
