My advice is that there feels like there is a little fence anarchy but at the same time, it doesn't? It's a weird balance with the little area change at the bottom left -- does there really need to be an area swap there? If anything I rather see you introduce splashes of brick throughout the whole area with tarmac rather than separate the two. I think that would up the consistency and make for an overall cohesive area for the coaster.
In the spirit of fences, maybe push some spots back away from the path. I get you need them for protecting guests from the coaster, but having them a tile away from the path with some mulch/gardens/planters could boost the atmosphere and allow more chances for interesting foliage clusters.
Overall, good stuff, maybe your best! Looking forward to this one on the parks page.
