It's a pretty fun site - they're still working out a lot of kinks - the biggest being that the server isn't big enough to handle all the traffic just yet (so the site keeps kicking people out). Anyway - it's quite nice to go through the books and further experience the world of Harry Potter. The nicest thing is there are a lot of unpublished writings of J K Rowling about characters (and backstories), objects and scenes.

And I guess it's not terribly accurate to the story...because Harry Potter was never in his cupboard under the stairs reading his Hogwarts acceptance letter...but I could clearly see it in my head and wanted to draw it...it seemed like a nice reveal - to have this kid who spent the first 10 years of his life in misery and to suddenly have that all flip to become the most popular kid in the entire (wizarding) world with the arrival of a single letter would be mind boggling.
Here's the Adobe Illustrator cleanup:
I was hoping to convey the mix of emotions that would hit Harry upon finishing the letter.
