A small, simple and good-looking track pack, I like it, both of the current maps (especially Sakura Serenity) have super pretty looking visuals that aren't too distracting while still making the tracks look more stylish than your average track, as well as the addition of blue spheres to make the races more fast-paced and interesting, only concern would be the lack of a real challenge as both tracks show themselves pretty easy in difficulty, while this itself may not be that big of an issue, on small player-count matches it can really make them sort of boring.
So far, one of the better packs I've played. Can't wait to see what's in store for the next versions.
