Hi! I recently produced a song (among others) with no specific genre, and for the mastering I wanted to be as dynamic as possible.
Knowing that Spotify has the standard of loudness of -14 LUFS (and because I am a person that loves the sound of the music from 70's to 90's) I tried to not overpass that limit, having the benefits of a high dynamic range (TT meter by Ian Sheperd measures my song with a DR of 10).
So this is the song:

But I don't have a good monitoring in my room nor a good pair of speakers, just headphones by now, so I am not very sure if the mixing and mastering sounds good in other audio systems, so tell me what do you think, what I can improve?
If you have even some criticism about the composition I will gladly read it.
