Great job, David. Your background helps provide a sense of movement to the piece. Marker application was very neatly done, enhancing the 3-d effect. What did you want to apply/add from previous experience?
David, your boys include a lot of details that make it clear to viewers what the image is all about. Colors contrast well and the boys are easy to distinguish from one another. A few minor gaps, but nothing that detracts from the overall design. Well done!
