Sorry to tell you that your map have been rejected.
The theme is not really good, it's not the best you can pick, because there is already a Dragon (Head) map. The build is not good too, there is only a little dragon head, which is not really attractive, and most of your parkour is floating around making your map messy. The parkour is also not good, it's a bit repetitive, and because of invisible blocks, your parkour is confusing and easy to exploit.
However, the parkour is varied.
Thanks for submitting your map, would be really good to see more maps from you !
