Example done for this week's Art Block Execution project over on the Tix-N-Roo tumblr-
This week is Imaginary Friends, and Fred was mine, from 4-5 to 13-14 years of age. We were the exact same age basically that entire time, and I doodled a few pictures of him at various ages, but some of my stronger memories of him are from 6-8 years of age, so I drew him then.
This is actually only the second image of him drawn, other than the other sketches I made in preparation for this picture- and the last time was while bored in high school, and unintentionally. (I decided that the picture was Fred after the fact.)
