You're kinda contradicting yourself by saying other's opinion is second priority and saying the map is to get an emotional response in the player. I'm sure you have a great idea in your mind, but the execution of the idea is very mediocre to the point i think this is made by me 7 months ago, this has nothing to do with your interpretation and central idea assuming you have one, this is the modding process if people can't understand your intentions you're only going to get useless DS blanket nazi mods, or people telling you to remap, and this is the fault of the mapper, not the modder, it is the responsibility of the mapper to make the most retarded unskilled player understand your intention of your map. There are lots of emotionally expressive maps, if they are successful in doing so, the only two feedback they're going get is "this is a good and effective map" and "I understand the map but I don't like how it is mapped". At this moment people are having a hard time figuring out your map so they're just going to respond with "this is a bad map" or "I don't understand the map" so they can't give you actual advice to improve your original ideaIt's really quite simple. I'm the most important player when it comes to playing my map. And this is honestly how I would say any good artist should be working, no matter what kind of art he is making. If people don't work this way, you get pop music. That's my theory anyway.
Also when you say you have a central idea, can you describe it in 5 words cause I don't have the slightest idea other than "it fits"
And if people can't figure out my map, so what. It's their problem. And even if people don't understand my map, I have still gotten useful feedback, three out of four mods so far has resulted in direct changes to the map (still not counting mazzivs mod). And as it turns out, there are apparently people that like my map: so far I have two favourites on it. It's not much, but if we follow your logic, that it's only public opinion that matters, that's better than your Utopiosphere map, because even though my map has less than 1/4 of the views your map has, it has 2 favourites compared to your map's 4 (one of the favuorites being mine, because honestly it's a great map).
At the end of the day, the only conclusion that can be reached, is that mapping is objective. I know this is not really very conclusive, but really that's the reality of it. I make the maps that I like. I then hope that other people will enjoy the maps as much as I do, however that's not my main priority. Beatmapping can be a beautiful art form, that can lead to a interactive musical experience I haven't had anywhere else. And it's expressing myself through my maps I enjoy doing. And if I make something I'm really happy with of course I want to share it with the world.
Edit: And when it comes to explaining my idea with this map, I can probably do it in one word: progression.
