Feedback on a photographer website, image-heavy

Hey guys,

I just finished designing a theme for my website. I’m a photographer and needed to have a light theme, focused on the images.

What I’d like is some feedback from you guys regarding the performance of my website. Is it loading fast, is it well structured?
I do not have access to a PC as well, so if you Windows’ users could give me some feedback on how things are looking, it would be great.

Any feedback is appreciated. Thank you very much!
