Super, Angel!
Great athmosfere, beatiful orchestration, and nothing in it what doesn't belong there (sometimes my problem).
However, two things:
1. for me, I would like to see the arrangement more intensified, I mean, I could cut this mix in a few large pieces and resequence them to another' mix, with the same kind of result (I think).
May be it's just that I miss some drama in the song like he is going.
In fact I could give this qualification to the most of your (brilliant) songs, so it's difficult to judge this.
I mean, this is obvious the way you do it, so what about?
At the same time I feel curious what would happen with this and other songs of you, if you would import some typical fx or space samples or rithmic fill elements, just to emphazise the function of the next part in the song: 'where are we now in the song, dramaticly spoken, when does the murder happen?'.
At the other side, if you would use this type of songs in a theater production, everything I've said before would be nonsense, so... the question is, what do you want with it, if my analysis makes sense?
Doubting about your skills to make magic and intelligent 'paintings' you don't need at all, so why not explore the arrangement a bit more, like if you would be absolutely sure to get a release with it?
Second, shortly.
I definitely would recommend you to put in a deep basedrum, with an open basic pattern, just a few notes.
As a start, you can think of the TR808 bassdrum.
More convenient for the listener (measure orientation), and gives the opportunity to emphasize the songstructure by effectfull muting (dynamics as arranging tool, shortcutting to my first point
).
Anyway, a beautifull and ahem tastfull mix, for sure!
Let There Be Music!
