Hello Qwiiz! I will be rejecting your map, unfortunately.
The theme isn't very original as we have many dragon maps, although they don't look much like this. I like the way you've implemented your signs and checkpoints though, good job on that :)
The parkour is a good length for a hard map. However, it's very repetitive, being mostly normal/ladder jumps. Try adding in ice, soul sand, slime, fences, walls, trapdoors, heads, etc. The difficulty is also inconsistent, as it goes from normal jumps to double neos, roundabout ladders, and other jumps that would be much better suited for an expert or even an insane.
The build doesn't seem to correlate with the theme, unless it's meant to be an outline of a dragon; if that's the case, I can sort of see it, but it looks only like the front half of a dragon and there's a line on top that doesn't seem to contribute to the outline at all.
Thank you for submitting! If you have any questions, feel free to message me in-game, on the forums, or on Discord (MCBYT#2023).
