You have only been opened a few weeks. It can take some shops months before their first sale has been made. For me personally, it took 3 months. You only have 16 items, so you need to keep on adding.
I will add also, that you need to have someone who is fluent in English help you write your item descriptions. This one has some things that make no sense....

Lastly, patience! Good luck!
