I've just found your store. You have some lovely things and nicely photographed too.
One of the things we have started doing is that we do a couple of cleaner shots with a neutral background. But we also photograph them in a home setting too so our customers can picture them in their own home. Of course lighting is the key, as long as they are clear a little subdued lighting is fine given you've already showed nice clean pictures too.
May I ask why you are only shipping in the US? We're in GB, but we ship world wide. We opened in January and have just had our 13th sale. We mostly sell in GB, but we have also had sales elsewhere.
