This was my process for a 1950s style pin-up for the fashion department. They wanted to keep it "PG 13", so I was constantly reducing the breast size, revealing cleavage, etc.
This is a retouched version of a painting I did many years ago. You can see the original below.
I wasnt particularly happy with this recently, specially the background. So I retouched it. Just a bit though, I didnt go completely crazy with. I figured that if I want to remake this, I'll start from scratch.
