Gem, I would just tell the contest holder that you don't have a shop and you don't normally sell your art so that you don't have a specific tier to fall under. If you look at the other tiers and see where you think your art would fit in and go from there.
Question? How do I know what tier I am for art? I entered a contest and they want to know what tier I'm in. O.o I dunno, I usually keep my HEE art manips to myself. lol
I breed apricot and frame rids, most my horses carry prl, lately i have let the free reign multiplying spree like bunnies and im overrun by an army of raging , eager to spread boys. Most are pretty young and great for fresh blood, new projects or to just introduce frame in herd since it cannot be captured for. ALL rated EEP combo !
