Holbein painting!

At work this is the art project being done by the boy I do one to one support with. He struggles with art so I said I would do one as well and this is what I've produced so far! It's in the style of Hans Holbein! How come I never managed to produce anything near this good when I was at school? I Don't like the nose but other than that I'm proud of this! Will blip the finished product in a few weeks time!
