I've never done a portrait based on a real person before. I'm not sure I'd be very good at it.
It'd be fun, you should try it out. If not him, just anyone. Might expand what you know ^^
Well, someone seems to have beat me to it anyway so maybe next time.
Well I could always do with some art, maybe alternate! If you want to practice with it, I would most definitely love to offer suggestions and constructive criticism. And the same goes for if you'd like to draw something else.
