Your map has been REJECTED!
This is for the following Reasons:
The emerald blocks do not fit the bird theme of the map, which is made tougher as the birds are simply flying there. Maybe some wool for clouds would have been a better idea.
If anything, the course is really really easy, due to there not being much parkour variety. Allow us to use the birds in more ways than just jumping on their heads to reach the next emerald block, maybe add some more variety there.
Positively, your map was unique in it's idea, and while the execution was not as good as we had hoped, there is something here.
Remember, you can always re-submit your map after improving it, or you can create an entirely new map! Either way, do not feel down,
