A picture of my dad doing what he likes best - taking highly professional photos of a pie he's just made in his kitchen. I gave it to him for Christmas 2012.
This was a real turning point for me. It's the first picture I've actually completed in a long time, and getting started on it was frustrating because my sketching skills were so out of practice. But with the help of some adderall, I kept at it, and I think it turned out pretty well.
I haven't had much watercolor training lately, nor have I had significant practice, so the fact that I got the green of the chairs to blend in with the warm yellow of the rest of the picture is a major accomplishment.
