Stampin' Up! I used Copic markers to color him in. Dark shades of blue were used on the pants to make them look (almost) black and dark shades of Cool Grey was used on the shoes. I highlighted the toes of the shoes with a white gel pen to make them look like they were patent leather.
My accent strip of burgundy is larger than the card base, just to give it a different visual look. On the inside of the card, I stamped a large "THANKS".
