B

Complete rework. I was frustrated at the loss of details in my processing so I tried a different approach

C

Decided to work a bit on a closeup. Had some blown out pixel and decided to do it a bit more artistic and use the smudge tool :D Still not very happy with the color, it looks a bit to "candy style"

D

desaturated a bit to get rid of the candy look. still the red is a bit to magenta but with selective colors I get nasty pixel artifacts...
