Hello Psou,
Unfortunately, I will be Rejecting your map.
The theme is original, as there are no maps with the electrical pole theme. The build isn't bad, however, some parts do feel a bit plain. I would recommend trying to add a bit more shape, depth and detail, to make the build overall more attractive.
The parkour is varied, you used a nice variety of blocks and items, creating original and enjoyable jumps.
The difficulty is quite inconsistent, try to make sure the difficulty is consistent throughout the map, as it can be hard to find the correct difficulty for your map if it changes throughout.
There were some sections that were not possible in 1.8.9, please make sure you test your map in 1.8.9, as that is the server version, and some jumps made in other versions are not possible.
Thanks for submitting your map! I hope to see more maps from you in the future.
