And some general tips too!
I used paint tool sai for this, but most programs should be able to do things similar. I also included my layers if it would help! Here is a .sai file. Here is a .psd too but it’s missing a few .sai things.
It’s a really fast style to do because it’s simple- it only took me an hour to draw! But this is not for beginners because it requires you to know a basic amount about layers and to be neat.
