Hello,
I want to give you my opinion on your track.
first, the guitar part starts to get really dissonant around 0:55. Is this the converters fault/ done on purpose/ ...?
There is an nice change of general mood around 1:12, but the voice beginning at 1:16 (is it a flute or a distorted guitar?) again does not fit quite well in my opinion. But the other guitar samples are quite catchy.
The brass coming in at around 1:34 also uses dissonances sometimes, but in my opinion, they fit much better here. I liked this part a lot!
One last point: in my opinion, this track is not aggressive enough for being a boss track. Can you link the original source or your original MIDI ?
