The melodic idea is interessting, but I feel you repeat it a bit too often, like for the whole duration of the song. I know that repetition is a big part of music but...idk maybe it's just not my thing. Also I don't feel like the tempo is 250. Sure, it probably is in your project file, but I'd say that the song is 125 bpm, at least that makes sense for me, given the "style" and "feel" of the track
