Interesting

I haven't listened to ALL of your music, but I think this one is the most promising and orginal. And I always respect artists who try something different.

I think music is about the emotions it evokes, and the imagery it conjures.

At the moment the music feels a little all over the place. Different musical elements don't match, and in my opinion, conjures conflicting emotions and imagery.

THE GOOD:
My favourite bits are the first twenty seconds, and the minute after 1:27. These are the bits I could use in an animation.
The contrast between the sharp, lone horn (or whatever it is) with the soft mysterious backing is striking and memorable.
As for emotions, to me it evokes loneliness and mystery, with a hint of desperation. It is also slow and purposeful.
And imagery? It has a slight middle east flavour to it. Exotic.
All these original elements merge together, and in my mind I can clearly picture a guy wandering the desert in the middle of the night, alone. Good music will spark peoples imaginations just like it did for me.
Do you see how these different elements complement each other, rather than conflict?

THE BAD:
The drums, and heavy pop beat. Not exotic at all. Kills the mystery and all the other original bits about the music.
There's nothing wrong with them, and in another song they could be genius
Do you see how these elements conflict with each other, rather than compliment?
It's a difficult line to walk.

Sorry I don't have anything more practical to say to you, other than with every bit of music you make, really try and find that core emotion and imagery and add to that.

If you made this song half as long, and more 'pure' (made it all sound like one song) then I would probably favourite this song... and maybe even use it in my next animation?
