First of all, I love this and am really excited to see it when it is complete!
There were a number of things that I really liked, especially the buildings and other 3ds elements.
I thought that the animated TV screens on along the queue line were an amazing touch, and really helped set the theme.
The occasional bit of sound/music in the background was also a very interesting but effective addition, and made it really immersive
The actual coaster had a unique and pretty interesting layout, and I really liked the pre-lift and lift segment.
I'm sure that a lot of these improvements you are already planning on working on, but I will share them anyway:
I'm not sure if you were going for the full gerstlauer experience, but there were a few sharp jolts in the track, an especially sharp one coming out of the immelman after the MCBR. Some of the track could do with some smoothing.
Some of the scaling of the 3d's felt off. The fences and benches were very low in the main plaza area, and the celling in the queue line was also quite low. I think that the person in no limits is meant to be about 5ft 8, so the low ceiling would cause problems for people much taller
The vegetation felt poor, I am sure that you are working on it, but there was a lack of grass and trees especially in the surrounding area, and I think that lots of vegetation could help push the aesthetics of this project to the next level.
I'm sure that most of what I have mentioned you were still working on as it is not finished yet, but I hope that it helped
