Random sketches of people I know

I dont know why, but whenever Im bored or got nothing to do I like to sketch people I know.
I know why, I just do.
Funny thing about this one is that I started sketching it at party my friend was having when I stayed at his place, so alcohol might have had something to with the start of it.

I had several versions on this one before but this the version Im most happy with, its still rough sketching on some parts.

Some failed attempts at traditional lineart though.
