Hi Mila,
I am fairly new to the Etsy Seller community so my critique will be purely from the perspective of a shopper. Your items are so beautiful, I love all the colors! I woud have to agree with some of the critiques I read, the only thing I can say is to take your pictures with the same black background so the colors really stand out. Also, I agree that maybe you should think about opening another shop to maybe get a fresh start. I did that in a way with my shop by simply changing the name to something shorter, and it seemed to catch on better. Other than that I think your shop looks great, and your about section truly conveys your love for what you do! Hope this helps a bit. I wish you all the best and lots of success!
