Jeff, I took a quick glance and came up with a few things.
1. The title of your home page is page 2, you'll have to figure out how to tweak titles in your app as it will help with readability and search engine priority.
2. The text on your nav buttons is a little too fragile combined with the shading, for easy readability on my screen. It also appears to vary font size across the buttons. Not sure how others see it, but I would look to make them consistent.
3. The pics of your lamps should probably go to individual description pages rather than just open as images, and you'll want to work to resize the images for consistency.
4. There's no pricing anywhere. I would like to see some ranges on a per-size basis, if not particular prices for the various items you display.
5. I don't know the protocol, but is referring to these as Tiffany lamps appropriate when selling yours, or is that an owned brand? Can you legally show a bunch of pics of actual Tiffany lamps to sell from?
6. I'm not sure I would do business with anyone with a no-refunds policy. I know you need some protection, but you might consider if some partial refund policy might be in order if requested before work starts, or if the completed piece doesn't meet expectations. Is there any guarantee of satisfaction or warranty?
7. You might want to review the copy on your home page. Try reading it out loud to make sure it flows the way you want it to.
8. The page your home button links to isn't your entry page. That was a bit confusing. The home link actually goes to a page I would call something like philosophy or the classic about us. Do you want a link back to the entry page?
9. Your footers don't have your name on the copyright and the terms of use/privacy policy links don't work.
10. The gallery page refers to the 14 dragonfly, but I think it might actually say !4.
11. There are some extra spaces between words on the first line of your work in progress page. Maybe elsewhere, but I didn't see others.
12. At a basic level, you should rename your images and pages more meaningfully. You should also create some sort of directory structure to make it easier to manage your images. Images and their thumbnail-sized versions should have a common name with some extension to differentiate. For example: dragonfly_14.jpg and dragonfly_14_thumb.jpg.
13. Some of your text looks like it was converted to images. You're better sticking with the pure text for search engines. Using key words, like tiffany lamps on your various linked pages will help you get better rankings.
14. Clearly, you're using quality stuff to put these together. Would it be appropriate to identify the brand name or other info about the actual electrical parts, or describe any higher-than-typical quality construction processes? Soldering? Wire gauges or types? Switches? Bases and fixtures?
15. Are there any common options that can be substituted into the designs? Maybe dimmers or touch switches, or different materials for the metal pieces for example?
16. It might be good to have a specific contact us page in addition to the order info page. You might also consider a PO box for your business if you don't want to publish an actual address. A PO box could be tough if you're going to be accepting UPS packages. You may have to let out your address, at least to confirmed customers.
17. Do you need a toxic materials statement of some sort? Is there lead in your glass and/or solder?
Probably more than you wanted, but we're watching the Gladiator extended edition with director's commentary and I had some free brain cells.
Good luck!
