Hello The_CareBear09,
Unfortunately, I will be Rejecting your map.
The theme is fairly original, there are a lot of dragon based maps, but none exactly like this. The build isn't bad, the main structure is a bit plain, so I would suggest trying to add a bit more shape, depth and detail to that, however the dragon is built well.
The parkour is very repetitive, as most of it is based around ladders. Try to experiment with a larger variety of blocks and items when building jumps, as this will make your map overall more enjoyable to complete.
The length is good for a hard map, but I find the map to be a bit easy, and would probably be suited better to a medium map.
Thanks for submitting your map! I hope to see more maps from you in the future.
