Good stuff man. Yeah, when we start a level, it generally drags for too long, you definitely know what it's like. Best thing is to specify a personal dead-line and get it done. A level is never done, only abandaned, It's only a matter of knowing when to abandon it. 
So far, no complaints about you modelling work. Modelling wise, it does look very good. The textures / materials could do with a bit of tweak though, some of them look bland and doesnt blend with the rest of the level very well, just reduce the brightness of some of those difuses, and possibly increasing the saturation and dirt amount.
Those orange rocks on the beach look a bit repetitive, although it was some very nice and smart rock placement, i would just play with the color a bit and give it a little bit more variation, also, good thing you painted the terrain around the rocks 
one of my favourite tricks as well. Place some decals in there as well, like dirt decals, just to give it more of a realistic and interesting style.
It's a FPS boys, we all turning into console pussies or what?
