I think your art is well photographed. I do think your shop could use maybe 3 times the stock you have now. Shop sections would also be helpful - maybe separate black+white vs. color, nature vs. glam, etc.
I would also develop your About section! The new Etsy feature really helps showcase your process and personality. Maybe show a few photos of you out on site shooting or your editing/printing process.
! I got a few more pieces I want to put up, however the weather is horrible today, and my flash is broken, and my glass work really needs light to shine :( Hopefully it's better tomorrow!
