It's an extremely interesting idea, and for that I commend you.

There's a slightly odd 'notch' on her arm, but my real comment is that in the bg I just get a slight feeling of... I dunno, it's like it's meant to be a crown walking past, but a lot of the characters don't seem to be in walking action poses, if you see what I mean. Also, they seem to repeat slightly too much, and not in a regular way.

If it was liek time-lapse images, they would be evenly spaced, but you have several fo the same close to each other and then a gap and a repeat.

I'm probably being far too nit-picky here, as it's a great idea and an interesting wall, I just thought I'd try and leave a more constructive comment.
