>>22256487I feel bad about what I am about to say, but I think it could help you a lot.
You have fallen down a polish pitfall.
The issues that you are trying to fix stem from mileage, not from craftsmanship.
In reality, the lines you've got on your current work are more clean and precise than almost every vtuber model you would see out there. Pic related. Every line is freehand, it's just drawn small enough and anything too messy gets patched a bit.
This is impressive for someone with little drawing background, but, this is probably way past the point of diminishing returns.
I'm sorry. I really am. I hate being that asshole. Please keep pursuing your dreams as hard as you can.
