First, I have to start off with if you use the right colour for lighting, it makes an effect. You did this perfectly! I don't quite get the concept at first, but after a little while I did <3 Lovely piece of work.
One of my favourite aspects of this piece is the sky and rain - the colour and you did them both perfectly.
I know someone who does photomanipulations (and they aren't bad at it) and she'd probably agree this was good.
Some people would disagree because of the darker side and colours - but person preference I guess *shrug*.
Anyways - 9/10!
