Hello ProfessorHomer,
I’m going to be giving you a -1 for the following reasons,
The theme of this map is unoriginal, there are no exact maps like this, however there are many maps that are mob/chicken themed.
The build itself is nice, however is a bit plain. I would suggest using multiple blocks of the same colour in your builds to add a bit more detail and depth, to overall make it look more appealing.
The parkour is good, could maybe have a bit more of variety in the jumps, but overall the jumps are good and well suited to the difficulty, and the map length is also good.
It might also be worth adding some coloured carpets in the path of the parkour to make it a bit clearer where you need to go, this isn’t a huge issue and it wasn’t too hard to navigate the map, but there were a few confusing parts, which adding carpets could make it easier to follow!
Good luck! :)
