Adventures in Oil Painting

I got an oil painting set for Christmas in hopes that I would have a go at teaching myself. I've done one oil painting before this one, but it was 8 years ago and I was still in high school. This is meant to be a gift for my parents. They've been remodeling their house and I was wanting to make something for their walls. There's some things with the anatomy and shadows that I need to fix, but I'm letting the paint dry before messing with it again. It got to the point where I was pushing pigment around and it started getting really muddy looking so I stopped for the time being. This of course is just the under painting.
