makes me wonder what the context is :)
Really nice picture, very moody and quite nice composition.
A crit I have is that the 2 darkest colours are too close, and if you brighten the 2nd darkest colour the 3rd one needs to be a bit darker too, but that works pretty well - I tried.
Other than that you could maybe work on your AA a bit, it is alright in some places and very sloppy/does not really work all that well in others. But that detracts very little from the overall feel of the picture.
This is a masterpiece.
man, you need to chill out. this is way too creepy and beauty as well, love it!
