I had the pleasure of making an illustration for a friend's character. From base desing, coloring to the final ilustration they had a lot of input on it.
My client wanted a simple, overall useable for any campaign illustration, that way, they can change the personality of their PC and the illustration had to reflect that 'blank' slate of a mage (draconic) kobold.
Overall their character is a laid-back little thieving mage religously following dragons, thinking themselves descendant of them.
