Uhh.. if you've noticed, everytime I draw a character they always look the same. It's actually really simple to do this and I'm sure you know how to do this, but if you don't I'll show you!
I use Ibis Paint X but I think this can work on other apps too.
1. I have an entire separate canvas dedicated to character bases.
(Use the square canvas)
(AND DONT MIND MY GALLERY LOL-)2. Draw stuff.
I draw the characters in the middle of the layer and renamed it to:
The object name(object show name)From there I just save it as a transparent png and add it as a new layer on a different canvas. Then I just draw the limbs and background.
It sounds lazy I know, but if your art style is constantly changing like mine then maybe this could help! Anyways, hopefully you found this useful.
See ya!
