Played it myself, and even tho I always try to stay as positive and supportive of a map that I playtest, I just can't say it for this map. The build is not original since the whole parkour is centered around a 2d minecraft skin, which is very overused in terms of being a skin, as well as in terms of it being a pixel art, which leaves the map without a proper theme. The jumps themselves don't have a lot of flow to them and variety doesn't change much. It all feels like ladders, neo's and fences (reminds me of old PK maps like House).
Overall I see this map as a reject. The best way to increase the odds of it getting accepted is to redo the whole map. Include some unique jumps (different sized cocoa beans, piston/minecart mechanics, squeezes, etc.) and make the build more organic rather than a boring and overused 2d pixel art. That way your parkour can be incorporated with the build and make it much more clean. Also remember to not try making your parkour too confusing or too overdetailed. People can get lost and/or confused and it may impact their overall enjoyment of a map. I appreciate you dedicating your time to build this, and I hope to see more from you in the future. Good Luck!
As a side note, I recommend reading this guide (
