Here's a Christmas card I did some artwork on for my relatives in America. I drew myself and my two siblings on it. My second oldest brother in the green came up with the extra words on the card.
I drew on the postcard as well :) Tim Hodge, a former Disney and VeggieTales animator was an inspiration for this as he always draws on postcards and Netflix envelopes. Here's his fan page, https://www.facebook.com/TimHodgeArt
