Hoi Nyodex,
Sorry to tell you that your map have been rejected.
The theme is not that original, because there is already 2 train maps (Thomas and Train), and 1 UFO map (UFO), but mixing 2 theme is a good idea, so there is still some originality. The build could be better, while the build itself looks good, it's still quite messy, try building your parkour on/in the build and not around, and try using a single main build and not multiple builds. The parkour is good, it's varied but is way too hard for a medium, or even a hard, but too short for an expert.
Thanks for submitting your map, would be really good to see more maps from you !
(Also please put the ID of your map, we were judging the build in your first plot instead of your 2nd plot by accident)
