Hi Emily,
I like your bags but as you say, there is room for improvement in your pics. Apart from the obvious (those that were shot against the ruled backgrouns are very yellow and it's difficult to focus on the bags themselves), I would iron the bags or fill them with something, paper of an insert to give them a plump aspect.
As a buyer, I also would like to know more about how you make them. Tell a little story, make it personal, that's how you create a relationship with the customers.
Good luck,
Anne
