Hi there OctopusOCD,
Im sorry to tell ya your map has been rejected.
The THEME of the map is original so good on you for that !
The BUILD is quite plain, with no variation in the stone. The inside of the build as well as the back have no details to it, causing it to look bland. Try adding variation to the build.
The PARKOUR has a fitting length for an insane map, but the difficulty was too easy to be an insane map. Some of the jumps were very inconsistent with super easy jumps then a couple expert jumps. Try to blend your parkour better to fit an insane and make the jumps a lot harder than they are. You should also consider changing the variation as there was very little between sections. Try to add more block varation such as water, flowerpots, trapdoors, etc.
Thank you for the submission, I hope to see more from you. Have a wonderful day !
