If I can be honest .......
I would prefer to see your title at the top left and all navigation down the left hand side on top of the black only.
I dont want to see a vertical scroll, they are bad enough at the best of times, especially when im trying to scroll through pics. Strict no no.
Keep the picture slideshow to the centre and right, make the black frame surrounding it the same thickness on all sides that it is currently on the left/right side. Make the frame more transparent as your background is beautiful.
Also make social bookmarking items just small icons at the bottom of your left hand navigation. That really doesnt need to be too groin grabbing, trust me, if I like your page, il add it!
Just my thoughts, hope they are constructive.
