Mischievious dude appears!

This guy here is a supporting character in one of my shoujo/highschool life manga I wrote and sketched but haven't had the guts to ink it. I started it, thinking it will be an oneshot (1-3 chapters) but I somehow liked how the story developped and thought I should develop it , because it had room to grow. But I'm seting it aside for later.
This is a sketch in pencil+liner (I used no.4 and no.1).Somehow looking at it as I write, I find more and more mistakes. :)). Oh, well...So das skinny fellow starts off as a bad guy and brings some intrigue in chapter 2. You can see the mischievness in his eyes. He has curly hair and wears punk, acts as a spoiled brat and is very kniving.
