Antanina, I think your shop looks great! However, I noticed that your item titles are kind of short which is no big deal at all but I would recommend from experience adding keywords really helps with views. When I opened my shop, I searched and searched for ways to get my shop noticed more and doing this really really helped me. I went from 5 views a week to 100+ views a day!
Also, 3 sales in just a month or two is awesome! With so many sellers on Etsy, most shops are lucky to see 1 sale in their first 4 months so keep doing what you're doing... its working!
