I believe, this is what people call an art study. I tried to replicate Burry from Shelter. I learned that line weight is important for good lineart, color picking is difficult, and little bit of blur makes things better.
And I also learned that I should not look at the Krita user manuals for the wastness of all that I don't know and what I should try to learn. There's just so much stuff that Krita can do. It's overwhelming and I will die.
