I'm starting to understand the theme more. I think this was focusing more on legs and buttocks along with some bones. I guess I was just so fascinated by the first picture you drew, I didn't notice it. It was interesting to see some people with clothes on in this. On one of the pictures on top, a bottom seems to match a women's top. It's just great work all over again.
Some of the pictures were literally black. I guess they were meant to represent negatives? I don't think you can do that in Photoshop or whatever program you used for this. The colored lines show good contrast. You should become a professional.
