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.
