Hello there,
I would give this map a -1 sadly. The theme is not original, since there's already a medium map called TrainStation that was added in April.
This map also lacks a main build, as in there's no main structure that the build is on, in, or around. In the future, try to make a structure that is based on the theme :) You can look for examples on recently accepted maps as to what I mean by main build on the server at /warp beta, or check the Accepted maps subforum!
There's also the issue that this parkour is mostly floating, and there's not much variety in the blocks used to make the jumps. There are also clear sections in the parkour (as in, you can refer to the parkour in sections by jump name, and not by checkpoint: the normal jumps, the pane section, etc.) Try to use more unique blocks to make a unique and interesting course! You can use heads, brewing stands, chests, water, piston heads, etc. in your parkour as some examples of interesting blocks.
The length is good for a Medium, so good job with that :)
Please note that while I may be staff, I am not a Map Judge, so I have no say as to whether your map gets accepted or not. I just like to give feedback on map submissions to help improve people's skills in the community. Good luck with your submission!
