i think what really ties everything together is the usage of piano arpeggiations through each track; there's a sense of cohesion that results from using said technique consistently. i was very satisfied with how "Confessions" turned out; i was looking more for something of a mysterious/darker side, like the characters in said visual novel confessing about the internal troubles they have which is why they'd hang out at school still. :~)
very good work overall! i wonder, as much as i enjoy the piano arps, if it'd be nice for them to sit back a bit more in the mix for "After hours"; i do appreciate that they give lots of space for the strings to dominate, however!
