I coloured it! I've been in work and watching Harry Potter twice in the cinema so haven't had a lot of time, but I think this is the fastest I've ever coloured anything!
It's mainly traditionally coloured, except I didn't finish the water in the top picture so I digitally edited that, then added more illumination to the image and few other details... Meh, it's mixed media.
Hope you like
