I don't understand those people. What do they want? If they don't like your art, why do they bother scouring your gallery? The same thing happened to my Ahsoka picture, so I know exactly how you feel... This is a fantastic picture, as I commented on the original. Truly beautiful.
I've found the original thumbnail via Google (although the full-size image isn't available), and it's a shame that people get so self-righteous about a simple drawing. Any chance of hosting the original somewhere else, somewhere not so prudish?
