Gratz on starting your shop, that's the first step that is the hardest for many people!
Your shop looks great! Try to get a banner and avatar image up as soon as you can, you can change it later as your taste and ideas change, but once you decide on a banner that you like, stick with it... It will be your brand that people recognize.
Images: Try to take pictures against a white, grey or other color of choice backdrop instead of the clear glass. The glass can make it hard to highlight the subject matter. You can make a second or third image include a champagne glass or other background of choice, but the main image should clearly show the customer the item...
Hope that helps and great job!
Anyone else feel free to add to mine! :)
