My meaning was the circuit design. You seem to have struck a balance between getting alot of track in a small space without it looking cluttered ans without it looking like you have just tried to cram track in for the sake of having more track.
There appears to be little room for scenery but the layout looks like it have longevity because it appears an interesting track to drive. Love those S bends - if you can call them that.
If it were my track the only anxiety i would have is the desire for more borders and less barriers but i know this is tricky when space is limited.
