The human muscle of a canadian

We're doing skeletons in art class. So I went through a medical book and found a photo of the human muslces in the head. I Drew a sketch of it before hand. To take what I want and then I scanned it. Went over it with the pencil tool in Photoshop and erased the pencil. That took me forever. I dont have a drawing pad so ...you can imagine the frustration. haha I made different layers for each part so it was easier for me. Then I painted it brown and color dodged it all. Used a canadian maple leaf and dodged,burnt,dodged with blue and then yellow and orange. dodged with pink and tried every random color. And then painted it brown and did the same process all over again. Just finished it and I am proud. Im not sure if it is done..But Id like to say it is for now.
