Good music with nice melodies and simple but I think effective arrangements.
Although it could really use some mixing. There are frequency clashing here and there, and leads are generally too loud :( (especially in the first track).
Also one note which can be dismissed as a preference, but maybe there's too much leads for an OST? Melodies kinda blur together when you hear them non-stop. It doesn't make any individual track worse, but just a thought to consider when thinking in OST format.
