Ahhh this is such a cool topic!! I love seeing people's roughs and process. And I agree it can make everyone feel better that art doesn't just magically happen complete x-x! Sometimes a blank page can be so intimidating...
Here's the roughs for a page from the comic I draw for, with the final art. I just do my linework right on top of these roughs, so I try to make them a bit tighter than if they were just layouts. I'm all about speed in my process. Because of this the roughs really have to reflect the ideas of final art, and it's the most difficult step for me ><
