while there are a few buyers here you can count them on one hand. it's best to push it outside the place using blogs, twitter, google plus, facebook, etc. and since you have no samples here to attract attention there is no reason to visit you. also to have a more pro appearance, - don't spell YOU - as U. i found discount codes don't really garner attention.
if you want more attention, add more words, advertise, put things in groups and contests.
you'll want to set up galleries and sort your things into those. it's hard thumbing through random items like that and if your here for a while the amount of art will simply grow.
