Better than your previous bhop maps by far. The architecture is still blocky and everything is set at a 90 degree angle, so it looks a little dull. The 130+ propphysics should all be propphysicsmultiplayer to lower any network traffic associated with them. The skybox is set just right, but you should add diagonal hint/skip brushes on the 90 degree corners. A few things were missed with funcdetail as well, like the surf ramp.
