Hey Lana, I checked out your map, it was fun to play, but there are a couple of things that I think are maybe gonna have your map being denied.
-We allready have many maps like this, (skyblock on medium, Jungle ice and nether on Medium) .
-You can get the easy gems after basically only 15 or so jumps, that will make this map way too grindy.
-Whilst playing the map I found it to be quite easy, so I'd suggest making either the jumps harder or changing it to expert.
for the rest the map was fun to play, there were some cool new challenging jumps in there that I haven't seen a lot, I wish you the best of luck on the map, but I will suggest changing a few things.
