Hi There!
You can take what I say with a grain of salt, since I don't sell much myself. To be perfectly honest, I think your shop looks pretty good, so I'd say the best bang for your buck will be with advertising. Promote awareness of your shop and your items as much as you can!
For minor tweaks...
I'd suggest sneaking in some more keywords to your shop introduction. Examples:
I can never resist beautiful crystals in mermaid greens and blues
to make a casual, laid back bracelet! Or shiny glass beads in regal purples
for a necklace that makes a sophisticated statement! How about delicate pearls in soft shades of pink and peach
for a soft-spoken ring? Or smooth ceramic beads in fiery reds and oranges
to make earrings for the talk-of-the-party?
Review your listings to make sure you list all the materials. What are these separators and the toggle made of?
