This is a nice synth, might need some sort of fade out tho to emphasize power to it.
Now personally I'm messing with sidechain myself so I don't know much about it but I do know that it'd really make this track breathe well together and really put everything together nicely :)

Hope I was helpful, thanks for sharing it its not that bad actually, definitely all there.
