Angel of Death - Moleskine

Once again, I've gone a little overboard on a drawing, especially since this is supposed to be a sketchbook. I just couldn't stop drawing on that soft, luxurious, moleskine paper. I'd like to watercolor this, but i worry how the paper would hold up. Anyone have any experience with this?

I guess this is my surrealist interpretation of the Angel of Death. I never meant it to be so when I started, it just gradually built itself up to what you see above. It does seem a fitting theme to me though.
