Do things like put your textures on ingame and tell people its for sale, but before you even get that far post a WIP in the arts forum, people can give you constructive critisism on your art work and help make sure that your art is exactly what people would like. Also if you make an auction for it and make the first bid low, put the low price in the title, people loves sweet deals even if the tex isnt that great (not implying anything). So therefore you will get more views. Thats all i can think of
