Probably a dumb question, but what sort of pen or marker is used for the large black areas on your drawings? The sort of things I tend to buy either bleed through, have very little precision, or dry out prematurely, if not a combination of those.
Also, are these done without a sketch underneath? I've been wanting to ink my things, but my smaller pens die going over pencil. Or, maybe I should git gud and learn to nail it with just a pen. If they are, though, I'd like to know how to find pens that work on pencil.
Oh, and if this hasn't been hammered home already, this is fucking fantastic. Hope the exam went well.
