Revenge : Tickle the Highblood

So... I started this thing a long time ago, that's why the drawing style isn't as well as for my most recent drawings. I was bored and thinking to the previous drawings I uploaded, and when I thought to this one [link] I said to myself "Hey, what if Gamzee's "victims" wanted to have their revenge on him ?" and quickly sketched a thing. But I'm not satisfied of this one because I failed the coloring, there is proportion problems and the shadows under the characters are all shitty. I still upload it, though. Damn, I need to stop drawing when I'm supposed to study for my exams.
