Hello Repuloh,
Unfortunately I will be Rejecting your map.
The theme isn't that original, as there are already quite a few maps related to space/rockets, but none of this exact one.
The build isn't bad, it's accurate to what you were going for, but does look a bit blocky, I do understand though that it is difficult to fix that regarding the nature of what you were building.
The parkour is quite messy at times, there are a lot of floating jumps, and the direction of the parkour was quite confusing. I would suggest placing more signs or a different colored carpet in the direction of the parkour, since I found it quite easy to get lost.
The jumps are well varied, there were a couple that were impossible/extremely difficult with speed 1 though, so be aware of that in the future. The length did suit an insane map well.
Thanks for submitting your map! I hope to see more maps from you in the future.
