Guess Who?

This is the sketch for an acrylic painting. Finally doing something remotely artistic and I'm so happy about it!
This was done freehand using a reference. So the proportions might be slightly off but I don't care becase I loved doing this and I'm really looking forward to the painting part!
Anyways, I'll buy a beer for whoever guesses the portrayed person! tip: the hair is black, just didn't feel like wasting all the grapite since I'm gonna paint over it anyways.
