Cool synth and drums on first track I like the build up but its a little slow to build, its missing some ingredients, keeping the arp going forever does not work after more than 30 secs looping if you want to keep it going add something more or go somehwere else for a moment and come back after to create some movemet.
Echoes is defintely better in terms of pacing, there is a nice story telling behidn the music, the only thing to look for is the stacked chords on piano and strings, if you change the voicing a little bit it will help the mix and tone so much, it will sound wide and clear. Good job !
