first impressions always happen within the first few tracks of a game — "Echoing Cries of a Sentinel" fits the bill as a good first impression for me. i ADORE the usage of chromaticism throughout your pieces, and the prominence of the piano and certain lead synths keeps everything cohesive. :3c
you did amazing with bringing the whole atmosphere of the game together!! i love the variation in atmospheres throughout. also echoing the sentiment that it would be nice if you had more time to mix; but the concept and arrangement of everything is great!
