Unfortunately, I will be REJECTING this map submission.
Theme: I can't really see a theme here but it's mostly just the nether. So, as we have an overabundance of biomes/nether-related maps currently on our server, this is a very unoriginally themed map submission. I recommend that you look at our list of previously used maps/themes as to prevent such things: https://docs.google.com/document/d/1lZKQZMgGev6fXyhZ8nCPkTzNIj0yOjXjUTDvfzKNzl4/edit .
Build: The build is not very good. It's just a poorly-executed floating nether fortress and ghast. Besides its unoriginality it really doesn't convey the theme well. There's no focus, detailing, or shaping. It's just not very attractive.
Parkour: The parkour was long and easy enough for the easy difficulty. But, I found it to be really linear. You divided the parkour into similar segments which proved to be very unenjoyable. You'd have multiple 1b's or multiple hh's or multiple ladders consecutively. You must be more creative when making parkour.
I hope you take these criticisms into consideration when submitting maps in the future, good luck!
