Yeaaah man this really is some good shit! :D Regarding that higher volume, might it be an idea to switch up the volume in the track itself, so that it may within for example a playlist be enjoyed at as adequate a volume as surrounding tracks too, if they happen to be optimized for loudness? Not so anything clips mind you, but it does seem the overall mix could be pushed up a bit...
Strings do sound powerful. It builds nicely. Feels like it doesn't truly reach the peak or crescendo it could reach, it just kinda ebbs out at the end; cuts itself a bit short but... still very cool.
Clean production too. Plenty of space in the mix. Nice work with this.
