I thought it was cool
~~REVIEW~~
So this was pretty fast paced as it starts into it, i like some of the tempo changes, that was a nice beat, and when it gets really slow you really push it forward so nice job there on the tempo change, was a nice option, as for improving maybe more of that tempo chnge even a build up of some sort would help aswell, so you can try a few things to improve but overall its pretty good.
~~THINGS TO IMPROVE ON~~
As suggested some tempo changes, even some build up changes wouldnt hurt, give it a try and lets see what happens anyways good stuff here.
