Nice layout, very easy navigation, clever theme, fantastic photography!
Very minor suggestions:
•Remove the watermark from your main photo (index page). It's hard to read and is a different URL than your site and the photo links to a subset of your Gallery anyway--I don't get it. OK, I see the watermark on the enlargements elsewhere. Hmm. I understand your desire to protect your images, but it makes you look paranoid, perhaps.
•Maybe add text labels to each nav image on the main page telling the location (they all seem to direct to a different part of the Gallery).
•Correct the typos in your text headers on some pages (lack of spaces between words, missing characters).
•"I have not yet set up a link to Paypal." Get it set up before promoting your site ;-).
Hope that helps! LA is a long way from where you are, but some day I hope to visit. My ancestors were from Ireland.
