This is quite cute. I've never really thought of Cry and 'Sup guy like this.
4 and a half stars for originality. I think it's rather original if I do say so myself. Not many comments here.
Your shading and lineart technique are great, and very pretty. I do suggest improving a bit detail-wise, for things such as hair. Another suggestion for if you do something else like this, perhaps add a sort of fading effect for the light bulb when it changes colors. Either way, it looks very nice, neat, and well done.
Not quite sure what to say impact wise. I do really love this picture though. Very cute, and your drawing style is wonderful. The way you drew the 'Sup Guy is adorable. Well done, you may have just earned a new watcher.
