Thank you so much Bodo!
I still have the first song of yours I ever heard on my playlist from Redlines composing challenge.
I think you're probably right about the timbre. Before I started composing anything, I got all of my instruments set up to use for the entire OST. The only instrument I ended up adding was the xylophone after about half of the songs because I really wanted another instrument that wasn't breath based (winds or horns). I did that so I could make sure the OST stayed consistent whilst also giving me room to mix and match things. Like the piccolo, harpsichord, oboe, pan flute, and others only play for some and not all of the songs. That was my attempt to keep things fresh. Though I still used many instruments in every song such as the Celtic harp which I'm fairly certain was in every track.
I would have loved to put more instruments in, but to be honest I couldn't think of that many more that I not only had easy access to, but didn't overlap too much with what I already had.
Perhaps I should have changed the mixing on some to keep it more fresh. I debated making Take stock much drier in the mix to simulate being in a small building, but it seemed to different from the rest and I thought it might sound like a mistake.
