Thank you so much for your insightful feedback! I'm glad you enjoyed it. That solo cello is the Tina Guo library from Cinesamples. It's really nice for expressive legato stuff as you've heard, highly recommend it (It's also fairly affordable on sale given it's quality). The wooden percussion is a Marimba, though it isn't the most realistic sounding one out there so that's probably why you couldn't put your figure on it. It works quite well the piece though. For track 5, I honestly was having a lot of trouble making it sound right, so I completely understand what your saying. I changed the instruments a lot and mess with a lot of different effects, but in the end, I ran out of time so I just had to upload what I had. Given more time, I probably would make it mesh a bit better with the rest of the soundtrack but it is what it is.
I really wanted to push myself to try a whole bunch of styles because I'm still experimenting a lot with music production, so that's where that variety came from. A missing sense of identity is a valid critique though, and it's something I'll surely improve on in the future. Thank you for listening!
