A couple of things.
You need to defuse the light for your product shots. The reflections are distracting.
You need to fix your descriptions. Read this out loud to yourself and see how awkward it is. There's also a typo.
"Add an artisan touch to your home decor with this hand-painted turquoise and white vase! Brush painted with high-quality acrylic glass paints and cured for 2 hours in a low temp oven. Each color in individually brushed on and allowed to dry before adding the next color, giving the vase great texture. All vases are back-painted to add beautiful dimension.
Color: Turquoise, White
Dimensions: Height-7", Opening 3.25""
You've managed to put the color in the title and in the description - though this is not necessary because you have a photo. Guess where you didn't put it? In the tags. Why isn't one of the tags "Turquoise Vase"?
When I first looked at this item I assumed that it was ceramic. It's only after I looked at your materials that I saw that it was made of glass. You should mention that in the description. The materials list "Enamel paint" but the description says "acrylic glass paints". Are they the same thing? If so, why not use one or the other? If not fix whichever one is inaccurate
You also have useless tags; "elegant", "art". "blue". Do you really think someone is going to type "elegant" into the search box?
I also think you should get rid of the Ebay style pricing. My experience on Etsy is that $40 reads much better than $39.99
>"All vases are back-painted..."
Who cares about "all vases" why aren't you saying "THIS vase?"
And what is "back painted?" I don't know what that is and I am sure I am not alone.
Your policies need to be cleaned up;
"If you wish to use another form of payment, please feel free to contact me and we can determine if something can be arranged."
Doesn't exactly roll off your tongue.
Plus you're giving prospective customers a reason to hesitate. You already have many payment options.
