An excellent example of commercial animation.
I'm not sure why everyone seems to be so upset over the fact that this is advertising a book. It is still animation, and a perfect example of commercial animation which I might add is completely valid. As animators we must all remember that not all of us can get jobs creating TV shows and movies. Just like a traditional artists, some people need to design and illustrate and not everyone can make fine art for galleries, it doesn't mean thats not valid art.
More directed to the movie, I think you did a decent job. The illustration style was done very well, if anything I would work a little on the movement and as far as commercial animation is concerned I think the typography was a little too simple. Other then that, very good job and ignore the pretentious reviewers that are apposed to this. Animators deserve money too ^.^
