I has come to comment.

You might want to smoothen out your cropping. I'm guessing you used Photoshop to make those (correct me if I'm wrong), so it shouldn't be a problem. Your animation is okay.

Also, you can try static signatures. This gives you a chance to explore filter effects, gradient maps and other random effects including using C4Ds. Then you can combine both.
