I'd put some guard rails along the roadway at least.. since you've got a drop into the water on both sides. The green bridge is interesting, but I'm not sure what the whole green structure is. If it's supposed to be a structural bridge truss, I'd try angling it inward on both sides. Your foliage and land types are still hugely random, and I think you could benefit from cleaning that up a little bit. Besides that, looking pretty nice-- the hotel is improving.
