Every year I send out holiday "Thank You" cards to all of my clients. This year I decided to design and illustrate my own. I'm having them printed by moo.com, they're awesome. I highly recommend them. [link]
BTW the inside of the card says "Or the panda will steal your presents and sell them on eBay"
I sketched, illustrated in Illustrator CS4 and added a little texture in Photoshop CS4. Approx 5 hours.
