They are really good. like other people have said not many people pay RLC on here- maybe you could charge rlc for the bigger time consuming pieces or something? Ive seen that done before and then the smaller pieces chibis 400-500 and then the ones with a coloured background different style types maybe 700?
Personally I'm not a fan of auctions because they all come down to some rich person getting the highest bid (or the AB which is meant to be super high).
I prefer posting an order form and commissioning for a set price.
