Ooo orchestration
The use of the instruments are pretty conventional, and the stabs that are in it are fairly well placed. There are some parts towards the end that are arranged quite nicely, which kept my interest well enough. There are quite a few things that could be better, though.
The instruments don't sound human. They really sound like a computer playing the parts. People do not attack the notes the same way throughout a song, nor do they stick to the same dynamics. When writing computer orchestral music you need to be paying attention to how a real orchestra would be playing the music, if you want it to be convincing. Set your velocities to affect the volume and try to make the sound a bit more human.
lThose pizzicato strings are... um, a bit too insane, there, for any human being. It's just not possible, so you should avoid it, if you could, since it really takes the listener away from the realistic atmosphere you're trying to create, here. A harp glissando and/or a piano would serve you better, for that reason.
The mixing is a little sporatic, there. While I hear the panning is correct for an orchestra (nice touch), the ambiance and spread seems too extreme, so lower the reverb to a less church-like and more hall-like setting, and fix the spread on your instruments/master channel (whichever it may be).
The bass tracks are too quiet, here. I'm not hearing enough in this to ground the rest of the track. Mind you, since this is an orchestra track simply raising the volume might not be a good idea, so try to achieve the volume by doubling the bass with a bassoon, tuba or something like that. It'd help give depth to the track.
Y'know, I think I've seen you post something on the OCR WIP boards, haven't I? I think I've heard your other stuff before. Ah well, it's certainly a good effort, here, and I hope my advice helps.
