Keith,
Welcome! Very nice work! And CHEAP TOO! LOL!
I would raise your prices and probably start in the high $20's or more, as "price" here isn't the first factor for many buyers, but the image and the uniqueness of that image. Find other artists that have a higher price structure and then "borrow" theirs!
Visit "recently sold" and see what is comparable to your work and see the pricing, for a good guideline,
Hope this helps,
Rich
