Nice, very nice.
I just wish you had e-mailed me saying that you'd released this.
My only problem is that it felt rather rushed. You need to develop things a bit more, but it's a very nice start. Will Harry start trying to develop class abilities, or try to model himself after a particular prestige class?
As for magic level, I figure that, because of natural talent, Harry's got a caster level bonus of at least +3.
Hope to see more soon.
