Well, I haven't watched the movie yet but I really like your drawing! I love the colours in it, the green touch makes it very interesting and the darker colours are wonderful contrast. Moreover I like the way you drew the guy - he's got a very cute look and I the hair. I also love the blurred Background, it's a brilliant Addition to the beautiful Picture.
very well done, you did a very good Job and I really like it!
Second, you should start watermarking your art with deviantart's watermark option for the time being. The first person who comment on this, Nightflight--Versel, stole it and posted it their own gallery. He'll keep on doing it.
