Hey DeBlobby,
I'm sorry to have to tell you that your map has been REJECTED. Although there is no accepted map with the herobrine theme, it is a heavily submitted one (commonly rejected as you can see). In this case, it is technically an original theme. The build is not very attractive and looks generic/unoriginal. There are similar player model builds such as "SkeletalSteve", "MapJudges", and "Admins" which all feature this type of rectangular and blocky type of build (which is no longer viewed as attractive these days). The PK length and difficulty definitely matched the medium difficulty, I applaud you on that! The variation was there, but, there was a common theme of ladders throughout the map (try to switch it up!). Overall, it's a map that features a poor/unoriginal build with very promising parkour, so keep that in mind for next time. I hope to see more map submissions from you!
