Hoi PaytonG,
Sorry to tell you that your map have been rejected.
I don't think there is a theme in your map, I more think you build a parkour without really thinking of a theme before, so please try picking a theme next time ! The build is not really good, while I think the sort of castle at the end looks good, the rest looks quite messy and unattractive, try building your parkour on/in a main build, and not floating around like you did. The parkour could be better, it's a bit varied, maybe a bit repetitive, but the parkour is overall good, maybe a bit hard with some jumps ?
Thanks for submitting your map, would be really good to see more maps from you !
