Laura, I think your tItles are okay- I think you need cohesiveness, though. Some of the words are capitalized and some aren't. I would go through and change all the first letters of each word to be capitalized.
I also noticed that you don't accept gift cards- is that not an option internationally yet?
Another tip, I get a lot of traffic through twitter. You should definitely look into starting one- I know there is hesitation based on the terms and conditions, but you can post things about fashion, illustration news, or even a sale going on in your shop!
Make sure you're updating your listings as well. Whether it be a photo/ title update- the more updated you are, the more relevant you become to your keywords- which is why Search Engine Optimization is so crucial.
Laura, if you have any other questions, please feel free to direct message me! I would me more than glad to help :)
