Initial impression: the images on the landing page are not compelling, both looks-wise and technically. This is the place you need your most stunning and compelling images, visually captivating and technically flawless. You have much better work inside, and none of the pictures you used would make me look any further. Sorry if that's blunt.
It feels slow to use, and the gallery images seem to be buried several layers deep. I know you're trying to specify down through landscapes to locality etc, but it *feels* awkward. There's a button for Select Photos that does nothing. The sharing feature is neat.
The About page has an empty placeholder and typos in the text (lower case i for I).
The Contact page has another empty placeholder next to the contact details box.
