I've missed some well composed orchestral tracks. I'm glad to find out one from NG.
I'd like to point out some things I got while listening your tracks. You probably already know the things below:
- 0:37 building violas(/violins?) could have more stereo sound and a bit more low frequencies.
- 1:08 -> mid and high frequency instruments to have more stereo. Before this section it's suitable to have a small range strings but after such a build it is good to expand the stereo ranges.
- Some instruments could be panned a bit left, some right, like if you were listening a real orchestra (positions).
I guess with a proper mastering tool you would make wonders! :)
I also listened your other tracks from your websites. In my opinion your tracks have something to say and they are well organized & composed. Your main VSTi for these orchestral instruments may be enough with accurate pannings and frequency adjustments. Just a little bit more "ear" into final mastering and mixing and that's it.
