I was browsing through some artists pages on Twitter and I found these images:
From this Twitter post.
I'm new at digital drawing, so I don't know how to ask, or what to look for in order to find out what it is, so I have two questions:
What are those blue lines outlining the line art of the first image? Is it done manually with a brush, or is it some effect layer?
Also, what is it that makes the image look "granulated"?
I'm not sure if I'm being clear enough, so let me know if you need more information. Thanks!
