Update!
I've worked on this a lot over the past week. Landscaping is 100% complete, and all thats left is finishing the custom supports, foliage, the coaster details (Station, Transfer Track, etc.) and then finishing touches. Here are 2 screens. The first is of the Cave Cafe, the second of one of the 3/4 instances in which the coaster goes underground. (If you consider this underground.)
I'd say the design is about 80% complete at this point.
Comments are appreciated as always.
