Even though it's not really a colouring tutorial exactly ¯\_(ツ)_/¯ IDK WHAT ELSE TO CALL IT HAH
Just a bunch of tips and tricks I use to get myself looking more traditional, I guess ;0; I few people asked how I achieved this look, so I've done my best to explain my process.
As stated in the tutorial, this is with Manga studio 5 EX/
Clip studio EX (exact version being 1.3.5) and I don't think all of these techniques can be applied to other programs, but I'm sure there's other ways of doing it better suited to things like SAI or Photoshop.
I'm not sure exactly where my brushes are from anymore- I remember getting them in a pack a long time ago, and the Gradients are from Clip's online store.
