As a consumer, I would probably need more "window dressings" to spark my interest. Having the one listing, even though it does say various colours, doesn't really inspire me. I would make a few listings of some different colours so people can visualise the finished product and makes your store page look more attractive. Would you consider doing a ballet flat type style as well? Same as sun42 above, I can't wear heels like this. I like the idea too of photographing all the glitter colours outside the bottle somehow for a nice visual.
Also you can put a link to your Esty in your Craftster signature and get posting and commenting on the boards here to get your name around.
Hang in there, two weeks is still early days. It looks like a really awesome product!
