Shocked this doesn't have any reviews, and sorry to hear your uncle is no longer with us. Hang in there. You made no mention of how close you were, but that's neither here nor there. Death is all around us and no matter how much we say it doesn't affect us, it's there.
I think you made the best of bad circumstances with this song. I think the most that could be improved would be to bring the hihats and cymbals down somewhat, bring up kick and snare, and bass as well.
I'm not the biggest fan of the autotune effects on the vocals. Perhaps they could be used more sparingly, or more effects applied so that they sound like a transmission from space/to space.
I think this might have more of a place in Punk due to vocal delivery, but this is irrelevant to the rest of the review.
Solo at the end makes the track pop.
