You should do other people like this, your style is amazing! You show the characters the way I imagined them while reading the books! (especially Percy, most people draw him without curls and he didn't have glasses in the movies....)
Yes, you must do more portraits!! This is awsome! I like that it is your own Harry, thats to say, very much like i imagine him, and as he should look like, because I dont think Daniel Radcliffe looks like him at all. Love-dovey!
