I would recommend that you check the theme and reading jump requirements before making a map, there is already a map that is very similar to yours, and there are too many jumps for an easy.
Build wise, its too wide to be accepted, and the wave was made with worldedit spheres. Typically, you shouldn't be using worldedit for the majority of the build. I do however the like feeling the coast of the map gives!
The parkour is too long, as I said above, and you did have some variation in the jumps, but a lot of the same type were grouped together which is a big no no. Additionally, the parkour is way too hard for an easy, and I do wish that you got to parkour around the wave more rather than going under it for the entire map.
Please don't let this discourage you from making maps, a lot of new people, and even experienced people use themes that have already been used.
