Great colours. Love em. Fits your title well and makes what would be a pretty dull image really stand out from the crowd. I scored this pretty high (8) mainly for that. The smiley face on the finger just adds to the overall surreal feeling of the shot.
I think it would be pretty bad in the natural colours though :)
I really like this. It's so pop art, but with some kind of passive-agressive thing going on :). Brilliant colours. I can imagine this in a modern art gallery. 10 from me.
