It's entirely a matter of preference. For me personally, I just love to work on paper, and digital inks just make me extremely worried about the detailed thanks to unlimited zoom. The feeling of "this line is here forever now" is empowering once you're used to it again. Without CTRL+Z you learn to just keep going, own your flaws, and accept that you're creating the best you can do today, improving for tomorrow.

There's nothing wrong with digital inking, it has its clear benefits. I've done quite a lot with digital inks as well and changed back to traditional only last year with Life On Cora #3. Because they're lines that'll stay and I can't correct like in digital, it makes it easier for my mind to just move on and not get stuck on a single line that I have to get perfectly.
