Awesome site man! Like said above, watermarking images is a must if you don't want people to steal them for themselves. Also, the first three images as soon as you open up the page are cool but your name in the top left is really only visible on one of them. Again, that is the benefit to having a small logo watermark to make sure that people know its you without taking away from the overall image. Also, having the slideshow format is cool for the pics but it may be cool to have a sort of gallery option as well so its easier to navigate to a specific photo if needed. And one more thing, having a description below the photo about who is in it or where it is would be cool; especially for the nature and skiing ones.
The website above is far from perfect as well but if you scroll down on the homepage you'll see what I mean by gallery, having that with the photos in each tab would be cool just for ease of access and that wow factor as people scroll through all of them and see everything you've done displayed. As well, at the very bottom of the home page, this guy has links to his Facebook and Instagram. Idk what you have for either of those but it's nice to have some social media platforms or important links in multiple areas.
