Interesting instruments on the default library. Quite old school in a good sense. Overall result has quite a thick sound, very orchestral. You did well managing to remain the atmospheric feeling with it.
Drum start on the first one was perfect. I like the darker sub tone horn-like instrument adds before the second half of the song.
Nice waves on the third one. The no transition to bang-ish steel bell-like instrument was nice.
The only thing I can recommend - maybe make arpegios a bit more uneven. The second composition would benefit from more pauses or subtle changes in them.
Overall I think you made pretty cool tracks, well done!
