Hey, like the others this is constructive criticism. Honestly, this is a bit to basic for a parkour map and we get a lot of quartz maps. A lot. A very much lot. But anyway I would normally do a really long sentence but here is the gist of it: Use your imagination, try new things, just cause its parkour does not mean thats ALL it has to be. You can make an adventure, tell a story etc... There. The reason I said all of the above is because you put quartz blocks down, white stained glass and posted it. Parkour maps need detail, they need to stand, especially when its a common theme like quartz. I hope you continue to map make. Best of luck!
