B&W. Its probably because in the colored version, theres is alot of black, so the character doesn't stand out. I do like the colors, but it seems too simple, and the black is a bit much. Also the character is a bit blurry, so there isnt' much focus. Sharpness is the key also for attention. Giving too much blurr all over, won't focus the character well. Just looking at the eyes, makes me not want to look at it anymore.
Usually when something glows, it should be also effecting the other areas and especially in black area, alot brighter.
