I really like your shop and it is very nice. What I would do to make it amazing would be to try to use more natural and slightly brighter lights (some photos are just a bit dark). Also a few of the camera angles that were obviously meant to be straight are just a tad off center and fixing that could help some as well. Some of the other angles are a bit awkward and some are great. I would suggest getting a friend to look through the images and say which images look the best and which the worst.
I would also set up an about page so that potential buyers can get to know you better and feel more comfortable buying from you.
A big negative is that you don't give refunds. This may be a deal breaker but it might scare away customers. What might be helpful is to say you only give refunds before you have shipped the item.
I may be wrong but it doesn't seem like all of your items are in a shop section which may cause some people to over look them. And lastly a little more inventory (I know you have a lot and it is a goodly amount) would really help you out.
Once again thank you, I went to check on my about page and realized I forgot to do it. One of those things when setting everything up that I will come back to it. Until you pointed it out I had forgotten.
You may want to take down your holiday message, and I'm with Michelle about improving your photography... Other than that, I love your shop, and I wish you good luck (:
