I decided to deal with using the wrong shadow color by re-base coating and using the proper middle shadow. Then I went on to the deeper shadow. I need to go back and put in more of the mid-shade and smooth things out.
I'm also not sure about his legs. They are super bumpy, and it looks...a little weird. The box art deals with it by putting almost all of his legs in some level of shadow, leaving just the tops of the thighs highlighted. That downplays all those shapes in the legs quite a bit. I'm thinking about doing something like that.
