I'm not too familiar on how well photography does here. Do a search for similar items to yours here on Etsy. See how are their prices and if they have twitter, etc. because it helps if you have a following outside of Etsy.
My first thought is that it might be nice to see your art framed & displayed as the first photo instead of the second. As a buyer, the photos that you have as your second image would make me more likely to click on it.
