Really cool to see your session in the YouTube video, I use Cubase too :)
And it's nice to see actual guitar and bass tracks that you've played. I still need to learn how to make those sound good, I am still hesitant to try this!
Your ost has quite a unique mix of sounds. It would make the game have a special identity :)
The composition is cool! I like the dynamics of each track and changes of direction.
For example that piano part to finish the last track was a delightful surprise!
Well done :)
