Hello arohq,
I regret to inform you this map is being rejected. The theme is unoriginal, there are quite a few dragon themed maps, the one that has dragons very similar in style is ShrineFestival. The build is pretty good, the dragon is accurate to asian-style dragons and the way they are usually depicted.
The parkour however, is entirely floating around the build, which makes the build look very messy. In the future, try to attach the parkour to the build in some way. The difficulty is also far too advanced for a hard map with cross neos, ladder neups, etc. You didn't list the jump count, but the length felt about right for a hard map, or a bit shorter potentially. I did feel the parkour was varied (used many kinds of jumps and blocks) but it was not mixed (having too many of the same block or style of jump in a row).
Thank you for submitting this map! If you have any questions, feel free to message me here on the forums, in-game, or on Discord. Hope to see more maps from you soon!
