Hello,
I love this concept for a map!
Sadly, the build is an issue. As it's so small, there's not as much detail as there could be to make this look even better. There is also no texture as it's all made out of one block. I'd suggest making this build larger so you can detail and shape areas better (ie the face).
The parkour does fit the length and difficulty of an easy map so good job on that. There is some variation; however, the variation is clumped together which does make the parkour repetitive and less fun. For more variation, try adding things such as flower pots, glass panes, water, ladders , etc to make the parkour more enjoyable c; .
Also, make sure all jumps are possible in 1.8.9 as some jumps are impossible (the head to the full block)
I hope this helps
Have a good day/night
