Agreed with Ali, but also....
When you compare the two sides (left to right), it gives this "HEY! let's throw colour on a B&W picture!" feeling. (from left to right: ominus, cool, BLEH!)
The dots with the colours are a bit too spread out also, but if you ad just a bit more colour to the right, or make it lighter, it might work a bit better. Mostly, I dun like teh blue dots..... And the green on his leg!!
