Lydia, I would love to give you my perspective! I'm brand new on Etsy, so please please feel free to give me a few pointers and suggestions too, I would really appreciate it.
Love your cute items! Your photos are really nice, too, they make your items look very attractive.
I see you changed your shop name recently. I like the new name, but I feel like maybe your header could use some improvement? Maybe even just a color/font change on the letters "LYD". It just looks a little busy and disconnected.
While I love and use smiley faces all the time for personal things, I try to avoid them in business things. I think it's best to put your most professional foot forward in the PR department. Maybe check out the policies and descriptions of shops you really admire or think are very professional. Don't completely take away the fun personality you have, though! Etsiers strike me as liking realistic, fun sellers as well as professional! :)
If you have a blog, Facebook or Twitter account set up for your store, do link them in your store settings! Social media is an awesome way to gather followers and fans.
I really love your store, Lydia! I hope you are very successful!
