I'm going to leave a comment here, despite you acknowledging you've moved on. I would be very curious to see if you would eve revisit this with your current skill set, so we could see your progression. It's not a bad project. I am sad that your texturing in the first 30 seconds or so just get eaten by the rest of the track and vanish entirely. Thanks for sharing.
Please contact me if you would like to use this in a project. We can discuss the details.
