Also it would be awesome if you could get a more clean background for your items. My first impression when going into your shop was clutter and overwhelming STUFF!! Probably not really the first impression you want to make!
A clean white background is good for making your items stand out and seem higher quality. Here are some shops that I feel have done this really well:
