Pretty solid start, I like the archy and atmosphere you have going. Maybe try and work you foliage a bit to focus the coaster, rather than just placing trees around the track without any real purpose. Coaster itself maybe could use some work, kind of an odd layout it seems.
Great work! I agree about the greenery, you need more underbrush and a bit more planning involved.
I love those hat shops as roofs!
