I love the use of rainbow decorations alongside primarily red structures. Creators usually do rainbow only stuff or will incorporate white/black/blue backgrounds alongside rainbow decoration, so it's really refreshing to see a primarily red color have some rainbow accents. It makes it a bit disappointing when it drops that red accent and just sticks to rainbow only, which I noticed in wonduu's last part. That being said, KiwiPenguin also falters a bit on their last part, a bit out of left field and a bit too different from the rest of the level.
