All the prior bells and whistles, now with a whopping 50% commission discount and the chance to vote on each month's sexy pin-up art. Use your monetary clout to reduce other people to objects for your cheap personal gratification! JUST LIKE REAL LIFE! Demand that FractiousLemon draw artwork of favorite sexy comic and cartoon characters or torture those in the lower tier by forcing them to witness suggestive imagery of Dr. X making out with SpongeBob SquarePants or something equally grotesque. LET THAT MONEY CORRUPT, YOU FILTHY BEAST, YOU!
Also, I don't know, exclusive artwork of butts or something.
