I usually just wing it kinda ehehe but I always start off with a basic sketch to get my idea of how I want my body posed and proportioned (I’m using the default marker tool for this)
Then I ‘refine’ and thicken out the sketch so it’s lookin more like a body
Then I add on clothes on top of the sketch, just to get an idea of where I want things, it dosen’t need to be pretty. For clothes and such, pay attention to parts that fold more often then others, especially at joints and such.
Okay! Now we have out sketch done and we’re gonna go into lineing. Create a new layer and set the sketch layer down opacity (Remember to line on the TOP layer though, Not the bottom like it looks here)
I work with two different line tools one for thinner lines and one for thicker/filling in lines. Both can be used for lineing on their own so use whichever one is more comfortable
Then you line on top of your sketch layer (in the new layer on top, you dont wanna do it on the same layer or it will just be messy and you’ll most likely have to do it over again)
Then you hide/get rid of the sketch layer and viola! How I do my linework~ (You can also take the marker tool with a light grey and put in some shadows to where you think you wanna shade to give it more depth)
And thats how I do my sketches/linework! I know it might not be super helpful but t might give you and idea~
