We're cheering for you to succeed, but look at the mess around you.
There's so much I could say. Part of me wants to call you an idiot for literally doing probably the hardest possible thing you could as your first project and without a team behind you. The other part of me wants to praise you for nutting up and taking on something so challenging. I want to tell you how you're overcomplicating some of these renders, but there is definitely justification for doing it the hard way despite doing it on hard mode. Just know that you'll only get the support you deserve once you've actually finished this project.
But I'd definitely suggest you ask around to other devs about possible shortcuts you could take. Consumers are fed up with things taking longer and longer while getting less and less in return. It's not just games either. Wasn't long ago we got 24 episode seasons every year and now we get 8 episode seasons every 2-4 years.
