I’ve got a protip for my friends who tend to clutter up their drawings. Some of you do this out of a sense that more is more, or because your work-ethic tells you you should fill up as much space as possible in every panel.
Here’s what you should do: Don’t think of white space as an negative area you need to fill; think of it as a positive design element that takes effort to deploy. Do the work it takes to put well-designed white space into your drawings.
(Apologies for using my own work in “how-to-do-it-right” context. It was handy. The white in the doorway in the first panel in this page of line-art from Alabaster: Wolves #2 works pretty well. I wish I’d used more white to spotlight that creepy crucifix in panel 3.)
