I once thought about making a comic of redo-ing entire Korra stuff to make her a good character with a slightly different name and different personality. But she would've been a different character than the Korra we all know now. I dropped that idea later.
In a way, Redeemed Kuvira in Book 5 is similar to the better Korra I thought of creating, so I don't worry much about it. I am mostly glad I punished Korra and brought back previous Avatar Spirits
When I started Book 5, I didn't have money or any of art, programming, writing skill. I learned it along the way. If you really want to do it, you will find a way
