Ouch, his right leg must kill. Sorry man, no sale. This has no real resemblence to Rain and doesn't even come close what his character COULD be. The overall design looks cool, but the boots, the color pallet, and the designs are just not him. I'm all for drastic change, but nobody could even come close to thinking this was Rain unless you told them. With all of the white and blue this looks more like some kind futuristic, manga version of Sub-Zero if anything else.
I'll give you 3DPs for the picture mainly because I like the basic design, but some of the more technical flaws take away, like his right leg, the colors, and symbols. It's a nice assassin design, but it's not Rain.
