Hey man remember what I recommended?
- Have a theme to the build
- Build a structure to do with your theme
- Keep the blocks against the structure and try to blend them in to the build. The less obvious and in space the better!
- Add some varied blocks to your parkour like ladders, brewing stands, chests, fences, heads etc..
Most importantly have fun!
Ps - Have another read over the map submitting format as this format wasn't correct! Good luck
