Wow, Khin - you have a pretty amazing shop! :)
Postive things:
1) Beautiful photographs - I love the nice, simple backgrounds.
I especially like this one. Nice shallow depth of field:

Things you could work on:
1) Maybe try adding more items to your shop. I know it can be pretty hard (I'm still working on it), but I think its very important and it really helps getting found more in search)
2) Can't really think of much else. :( Maybe be a little more descriptive in your titles?
Good luck with your shop!! I love your about page, too. :)
