Hi there,
Very nice pictures !
One thing that I didn't immediately see were your contact details on your frontpage. They do get shown for a microsecond and then disappear (to the bottom of your page, after the pictures). So you need to scroll all the way to the bottom to find it (and scroll again, as more pictures are loaded).
I would put your contact details available on the top of your page as well, perhaps smaller or as an icon, as they would be useful for people who are looking to contact you and are not first-time customers that need to be wowed.
The 'browse' is strange on the very first page, when you can already browse the pictures there. You actually have a frontpage with browsable pictures plus a gallery on the second page (for which the browse link is actually for). Plus when you click on a picture you get a detail, but when you close the detail you are no longer on the original page but on the gallery page.
That confused me for a second.
Also, personally, some information on the picture would be nice as well. There are a few pics that made me wonder where you took them. Location, keywords would be useful.
Can you search pictures by keywords or filter them ? I would only like to see farm vehicles, for example, or only landscapes... can't find it.
Hope I haven't discouraged you, the site is certainly nice enough, I'm thinking more "user experience".
