Sunglasses

The sunglasses themselves are rendered nicely (though I'd either make the reflection brighter or the glasses more transparent), but I think you need to give more attention to the stone it's laying on; the diffuse and bump textures are too low resolution for a shot this close, and you can't bump map the seams on the stone when you're rendering this close, it's best to model it. But, the DoF is done really well, and I like the highlight on the sunglasses as well as the water, which looks really good
