Hi!
Your homepage is very intense, it hurts my eyes to try and focus and see the words between the bright pink words in the background. And, some of the letters of a few words are unreadable because they are the same color of the background words.
I think that you could use a banner like the one that you use in your etsy shop for your site header. It will keep both sites cohesive.
Like Barry Doherty said, ALL caps can really feel aggressive to the average person reading your page and can become somewhat tiring.
You only have about 10 seconds to really draw in your viewer in and you sell jewelry, a very saturated field, but you don't have any images of your work on the front page. I would like to see some just to get me drawn in!
As for your other pages, I feel it would be easier to view and search around if the background wasn't so busy :)
