You did a good job of mixing and mastering to my ears. The parts you've constructed could be useful for an editor.
I absolutely love this soundtrack piece. Kick ass drum tribal pattern from the beginning sets this awesome mood. The these killer horns come in the rythm as well. Total build. The just before the ends around 1:55 the entire arrangement goes to an unexpected soft turn. This is definitely a piece that can capture attention.
Really like your composition and of course the VST you use.
All sounds perfect to me.
You will sell this song, no doubt!
Another idea is to do different versions of your song.
