Bothering Snape

I found this old sketch and thought that it would be nice if I coloured it!
I'm entering it in 's contest of drawing Snape for his birthday. I just hope this has enough Snape in it. I think this is what he deserves as a present! XD

Btw, I don't remember why I made the characters look like babies... If anyone has an explanation, please let me know, because I'm lost! XD
