Hey Jack,
So while looking at the screenshots, I noticed that this map is not very attractive. I'd also advise adding a warp to this, or a plot number, because we cannot get to your plot otherwise (although I did find it with /plot h Jack_West 2.) I did this and did the parkour, and it is considerably easy and short, even though it is an easy level, you should try to make slightly harder jumps, with at the bigger blocks, having parkour go inside it. I also consider this pixel art. which is not acceptable now. But, the jumps were fun. If you make these changes, and make it more attractive (more fancy blocks, not just one consecutive block) you might get accepted.
Anyways, best of luck!
