Hello Elly_x,
I regret to inform you this map is being rejected. I could potentially see this map being accepted in the future after some changes are made, though! The theme is original, as there are no Wizard of Oz themed maps yet surprisingly. Good job coming up with a new theme!
The build is a bit plain to me, but I think it encompasses many aspects of Oz that people are familiar with. I think that the castle could be a bit more detailed (perhaps using lime/green wool to shade it instead of solely emeralds) as well as the road (with maybe yellow stained clay).
The parkour is pretty varied, but not mixed. By this, I mean that you used a lot of different kinds of blocks in your map, but they would all come in a row and were identifiable by section (the fence section, the ladder section, etc.) I also felt it was pretty easy for the hard difficulty for the most part. If you want help with making varied + mixed parkour, let me know! I'm always happy to teach those who are willing to learn so that they can create maps more effectively.
Thank you for submitting this map! I'd love to see you make changes, and again, if you need help, don't be afraid to ask! You can message me here on the forums, in-game, or preferably Discord. Hope to see more maps from you!
