You only have two great images, so I suggest you don't upload anymore until you figure out what you want to do and how to do it.
Editing a lot of images can be a pain, and you don't always get what you want on the first edit.
Make sure you set your default prices at what you want and price only the items you want to sell.
Personally, it is lost money, IMHO, not to price all the products and let the marketplace decide for themselves what they do and do not want to buy your images on.
If you have doubts if there is anything in the price box, place your cursor in the box and hit delete.
