I haven't played this map, but I want to point out a few things that stood out to me in these screenshots, that most people might not notice.
For the most part, this map is minimal done right. A very soft vanilla light source, soft shadows, soft fog fade, soft font, and mostly soft colours. "Neutral colours" is something people should keep in mind when designing a minimal map. I assume, at least I hope you've included a soft soundscape too.
