Hi! Webcomic artist here! This thread is a bit old, but I figured i’ll still leave my thoughts.
In terms of simplifying your style, chances are you’ll have to cut back on some things. Unfortunately, when drawing a comic you really can’t go as detailed as you’d like or else it will take you ages to get through one panel. Understanding what to reduce and when is pretty key for productivity and speed. This usually means reducing details. Me personally, I found a way to simplify my style for comic work by experimenting. The other commenter gave some good tips. It’s nice to have a general idea of how long one panel or character will take you to draw, that way you know what to expect and where you should cut out detail.
Some tips I have for you:
1- Don’t do lineart. Do a sketch and then clean it up, just color underneath that. This is sooo much faster than doing lineart.
2- Not everything needs shading. You’ll notice for a lot of popular webtoons and webcomics, they only do very basic shading and rather add atmosphere and depth through gradients on the characters. ~Illusion~ of detail is the fastest way to do details!
3- Save panels, heads, eyes, expressions, bodies, poses, etc to reuse again. Copy and paste is your friend! Most readers won’t notice if you copy that eye from 10 panels ago and past it. Readers tend to look at a panel for sometimes >1 second, they’re really not gonna notice.
It’s okay if you’re a bit on the slower side! It takes me about 2 weeks to get out 25-30 panels. You’ll get faster as you progress and make your own techniques too!
Good luck :)
