Build: Personally, I don't think the build is very good. Of course, the first issue is the similarity in build intention between this map and our "Wipeout" map. Besides that, the build itself is very plain and lacking as it's mostly just floating parkour. There isn't much "build" to it. You have to remember that although parkour is important to a map submission, so is the build. You create a build that conveys your theme properly and then integrate your parkour into it.
Parkour: The parkour fit the medium difficulty in both length and difficulty, although it was on the shorter side of things. The only issue I had with it was the repetitive nature of it. I'm sure you can see how many times you repeated a certain type of jump. Be it the ice segments, wool segments, or ladder segment. These are all just the same thing being done over and over again, proving to make the parkour very unenjoyable. Be more creative with your parkour's composition!
I hope you take these criticisms into consideration when submitting maps in the future, good luck
