Mysteries Will Unfold

I got kind of bored drawing ponies so I decided to do a realistic pic. I know there is a LOT to improve on, but keep in mind that I mainly draw cartoons and realism is something relatively new to me.

The reference pic is here: [link]

Harry Potter, Rubeus Hagrid, Remus Lupin and Sybill Trelawney + the 'Mysteries Will Unfold' bit are (c) Warner Bros. and J.K. Rowling

BTW, I owe a lot of people some gifty art - it WILL come, I just have to finish off my stupid art/maths/English/Japanese homework first.... ^_^;;;
