The reason why i dont post WIPS (bc they look like this XD)
Ok so, i use the line tool and just make tons of lines for shading and outline, blacks outline, green is finer details, blue is lighting, red is extra
For the shading itself i draw random shapes mixing between the hard lineart brush, caliography, and smth else i forgot, i have every outfit ive drawn so i also just take a photo of myself paintbucket over my hoodie or pants and boom i can see where some lighting stuff goes ITS NOT CHEATING IF UR TRACING URSELF >:3c (I blame covid and online school for teaching me this)
Then u just use the ibispaintX filters overtop and done art XD
(I'd be easier to jsut do speedpaint to show everyone ngl, also got my phone back so i might relogin to pixil art and do some doodling)
