I’d like to see a more subtle gradient on the navigation bar at the top, kind of like the one in your buttons at the bottom. I like the logo but I would probably nudge it to the right a bit so it lines up with your images in the main section. And maybe float those social media links to the right so they’re above the sidebar. If I were to get picky I would say that the body background sort of clashes with the plain white background on the #page div. But that’s just my opinion and I’m definitely no expert when it comes to visual design.
After taking a look around, it does look like you’ve put a lot of work into it :)
Good luck with your site :)
