Heyo! I'm glad to see you submitting your map! I've taken a look at it, and here are my thoughts;
THEME:
Personally, I'm not quite sure what the theme is. To me, it just looks like a bunch of coloured wool put into sections, which is already a map (Colors, the hard map). I did do some research on the two people this was based off and they seem to be Minecraft streamers, but in my mind, the only thing this could relate to is the Minecraft Championships, which doesn't really have anything like this within it. If I'm wrong, let me know.
BUILD:
There seems to be no real build here, to be perfectly honest. There is the spawn and a large patch of sea lanterns, but the rest of the map is all parkour. You need to make sure to include a main build so your map looks attractive, and not just like a large patch of parkour. Speaking of parkour...
PARKOUR:
The parkour is entirely floating, for starters. Secondly, there are way too many jumps for this to be a hard map. Like, just 4 more and you could make it an insane map! I found the parkour very easy with minimal challenges, and it was quite tedious to complete as there were a fair bit of sectioned and repeated jumps. For example, nearly the entirety of the section under the sea lanterns is ladder jumps. That's not interesting and feels quite boring.
Overall, this map doesn't feel like it belongs on Manacube, as it goes against nearly all of the things that we ask for. If you were to add a main build, make the parkour shorter (or the difficulty harder along with the parkour) and more interesting and changed the way the map is presented (and quite possibly change the theme to something else), you could have an interesting and unique map.
Good luck in your future submissions!
