Hello, I am going to rate this map a -1 for now sadly. Here are the following reasons.
1. Build: First of all, the build isn't very interesting at all. I know that you were going for William Afton from Five Nights at Freddy's but this build is just a piece of pixel art, and pixel art can not be the main build for a map. If you want to make William Afton, I suggest making more go a 3D-ish version of him and add more block variations instead of just being a big purple block of wool.
2. Parkour: The length of the parkour is 45 jumps which is very suitable for a medium map. But the main problem is that the parkour is quite repetitive and not varied enough. It really makes the map seem boring and not fun to play. Try adding more parkour jump variations!
Keep in mind that I am not here to judge the map, and I am just giving you advice on how to make the map better. I hope this comment doesn't make you lose interest in making maps. Good luck!
