Back in OST 7, I tried recording part of my piece on my clarinet. It sounded terrible so I cut it out and used a vst instead. Recording with real instruments is defiantly a challenge and I think it's really cool that you completely committed to it. The theme was very creative too, making this a very memorable submission. However, I think the tuning inconsistency comes through the most when you have all instruments playing in unison. I'm pretty sure you can cover up tuning issues a little by playing harmony instead of total unison (I don't know much about this stuff though so take it with a grain of salt). I will say it does give the whole thing a wild western vibe, so maybe you were actually going for that. Great work tho!
