Next time try optimizing your scene object a bit. This ride was really kicking my computer fans into high gear.
The trackwork is decent. Only a couple notable pumps like the one exiting the loop, nothing major. Shaping is definitely dead on for what you were going for, and so are the supports. I feel like the supports should be slightly thicker in places like on the first loop, but otherwise it's all pretty good. G's were very well controlled as well. The only other trackwork thing I can nitpick at is that the barrel roll at the end had super obvious banking differences between the entrance and exit. The exit "unwinded" way faster than the entrance rolled over. If they're somewhat consistent it's better. Hangtime is fine on a Gerstlauer (just not at 8mph in that loop, you don't want the ride valleying in a wind gust) and I think you had room to fit in a slightly longer roll or you could have started inverting earlier.
My main complaint with this ride is some of the pacing decisions you made. I get that Gerstlauer has spastic pacing and you did nail that aspect correctly, however that loop is taken too slowly. If you shrunk it a bit and had maybe 4 G's entering it so that it had a bit less hangtime it would have rode much better. The hangtime isn't a problem, it's that it's so high up and his like 8mph at its peak. That being said of all the issues for a ride to have, that ain't bad. The other thing you could have done is lower the track entering and exiting the block brake (while keeping the block brake where you had it). The entrance I can allow because some rides have a gradual entrance like that to function as a brake, however the exit didn't need to stay 50ft in the air like that. You could have dropped it immediately 10-15ft and had plenty of room to clear the track below it while making a nice headchopper. That would have definitely helped out pacing-wise.
Finally the environment is extremely well done and realistic. I appreciate the effort that went into placing the little sensors, scenery, fences, queue line, and all of the overall effort that went into this. The scene objects were a bit over-detailed, but otherwise I think everything was pulled off really well.
