It looks nice, for a start, and it loads fast. I love fast websites.
And now for some constructive criticism.
I don’t understand why there are buttons for some things, and then
there’s a text list for your products. You should have all buttons,
or all text. I prefer all text. Also, it’s customary to have a link
labeled “Products” or “Gallery” or “Catalog”, something so people
don’t have to search around to find out what you’re selling. The
"Sold Gallery" is good, because people like to think other people are
buying your stuff.
The photos are a bit dull. If you’re using a digital camera, set the
white balance and exposure manually so these will be the same for
each piece, then go into Photoshop and punch up the contrast. Also,
I’d like to see detail closeups of each piece.
That’s all for now.
