It looks like a fun map to freerun on but I can't get over how irky the colors feel. Dull grey tones absolutely need to fit the theme or be backed up by a strong, beautiful color, and the sort of salmon red going on isn't doing it, atleast for me.
The map would also come alive and have a lot more depth if you varied the colors of the adjacent greys, even if only very slightly. The 3 large platforms in the foreground blend into eachother for example
