Very, very good. Sounded to me like the bit in at the very end of a Mega Drive (Genesis) era game, where the hero (or anti-hero as it would seem to be in this case) retreats into the distance, having righted whatever particular wrong there was in his or her world. I think the distortion effect is very well used, especially the bit around 3:20 where there is a brief pause before it kicks in.
If I may be allowed offer one minuscule criticism, I think the drums are a little too low in the mix.
