Do not lower your prices!!! You do not want to under pay yourself. This is your business- you need to make money. It is good to have some lower price points- I would consider adding prints or cards of your work to achieve this. But don;t lower the price on your original work.
I would also add more items, you need at least a full page, and more is always better. The more items you have, the more chances you have to be found.
Your tags/titles also need some work. You have a lot of single word tags, and this is not as effective as multi-word tags.
