Ah, your stuff is cute!
Well, one thing that really jumped out at me is your photos. I don't really care what color the background is as long as it isn't overwhelming, but I would try to keep your exposure and lighting a bit more consistent. I noticed that some of your items looked really washed out in their photos, or were really dim, while others were almost too bright! Now, there are two listings that look good, but are quite different, so I'll let you decide which one to go with, or if you want to do something in between, but:

The second one of course is higher contrast and really pops, while the first is much lower and soft. They're both acceptable aesthetics, so pick whichever works best for you and do it for everything.
Hope this helps!
