Hey Sue,
I checked out your shop. Policies are good & look nice, friendly & trustworthy. You have very cute items there, but I also think it's pretty seasonal.
On top of that, I think you could improve your photos.
You're doing a good job on taking many different photos of the items & showing them from different angles, but I think you should choose a more neutral background & more importantly: one or two background for all your items to get more of a unified look to your shop. Also, why don't you put your clothes on models so that people can see how they look once they're on?
Also, something's wrong with you "about" page. Maybe you copied it from a word document and the layout got changed? There are weird breaks and the text ends in a comma.
Lastly, I think your banner is cute, but it would look better with a logo (or at least your shop name) on top of it.
That's my impression, I hope I could help you a bit.
Best,
Kat
