The lead shifting to harsher distortion is a really cool moment. Overall, I enjoy that the composition isn't too static and you're adding or removing parts frequently in the second half. As for advice, I think some more bass would be nice in the more intense parts of the song, panned in the middle to sort of ground the arpeggios that are switching between left and right. Also, but this is up to personal taste, a bit more percussion for example a kick and snare. This would give it a more consisten groove, so I also understand the decision to omit them for a more disorienting piece.
I like it :)
