Hoi ArtemisERK,
Sorry to tell you that your map have been rejected.
The theme is not really original, even if there is no "Savanna" map, there is already some "Forest" themed maps, please try to found a better theme next time ! The build is not really good too, even if the islands are decent, your map is really messy, because there is a lot of floating blocks/structures, try to build your map on/in one main build. The parkour is not good, it's really repetitive, since almost all your map is normal jumps, the map is also way too long for a medium, but too easy for something harder.
Thanks for submitting your map, would be really good to see more maps from you !
