New Business Cards

I've just ordered my third batch of business cards from Moo.com, who do great work if you're looking for somewhere to get some business cards printed. One of the things I like about their cards is that they allow you to have as many different images on the back of your business cards as you would like. In the past I've put paintings, art from flyers and illustrations from other projects on the back. This time around, I wanted my new business cards to have something that tied them all together, while still being consistent stand alone images.
I decided to do a series of character art, and tie them all together by having them complete a walk animation. Here are my initial test sketches, I made a few small changes to the final characters.
