Looks like you're making considerable progress, everything looks awesome! I was wondering though, do you need someone to help mix instrumentals? Just an idea I had but I thought I'd shoot my shot, feel free to reply to share your thoughts, good luck with the rest of development!!
It's just I noticed some instrumentals have snares/hi-hats that are too bright and loud, others have bass that is either undertuned or lacks the impact it should have and some instrumentals have overall mix issues where some instruments become drowned out by more prominent ones. I'm quite good at mixing instrumentals, I have a few beats I've worked on to show for it and a few covers I've worked on for a content creator on Youtube, and it would be an honour to help you! Maybe I'm just chasing a dream, but if you see this LJ, could you please consider letting me help you mix instrumentals? You would still have full artistic control over each one, as you'd do the composition and arrangements and I'd handle the rest, I feel like I could improve the instrumental quality of Scratchin' Melodii's OST just as much as Mia has improved the vocal quality for the songs! It would also be one less thing you have to worry about, so you could focus more time on the art and code side of things for the game. I'd mix your instrumentals free of charge too! You have every right to decline my offer, but if you gave me a chance, I wouldn't let you down!
