From what I can see you've done a good job scanning your work so that it is available in large size prints. I had trouble with that starting out too and had to do some re-scans to make my art available in larger sizes. I still have some that need to be scanned again but haven't had the time. The problem I do see is you have a very low markup on your items. If you do sell something you're not going to be making much. I'd definitely say to raise your prices, but don't overprice either. You do want to be sure though that if you have a sale that you can at least pocket enough to go get a nice lunch somewhere. Anyways, your art is unique. Do as much free advertising as you can by making a Twitter account, Facebook page just for your art, and you may even use Google + or some of the other social media but personally I don't have the time to do all of them. Also, you can set it up so that when you add a new item here on FAA that it automatically posts it to your Facebook & Twitter pages. Good luck! :)
