How can I do more appealing linework? Should I be using stabilization, should I be mostly zoomed in or out?
I think the quality/expressiveness of my lines comes down to the brush I'm using, cause I can be more free with certain rougher brushes (which lets me get a better result in a shorter amount of time). I want to produce actually impressive lineart though, when I'm constrained to tracing an idea I've sketched I'm fucked no matter what brush I use. How do I get past this?
