Heya there Jack!
If you wish to submit this map, you can always do that under the "map submissions" tab.
Sadly this course is a skin and thus pixel art, if you didn't know, pixel art isn't accepted anymore. I however do like that you used different kinds of blocks: normal, fence and ladder. I think you would be able to make nice courses in the future.
Feel free to PM me on the forums or discord (Txilsy#7117), or hit me up in-game, if you need any help!
