Majalena: Your artwork is so interesting! Quite amazing. Don't give up yet - I think with some SEO improvements you'll have better success.
Mary can give you SEO tips, but I wanted to mention that you should go through all of your descriptions and correct the way you're using periods. Do you see how in these sentences there's a period, and then a space? That space is very important. First of all, it's the correct way to punctuate. Second, it makes your copy easier to read. Third, and Mary can confirm this, if you don't leave a space, it might cause problems with search engines - they might read your words wrong, or even identify your sentences as spam. It's an easy fix. Just could take a little time to go through everything. But it's probably worthwhile.
Best of luck with everything!
