Purposefully Dry Brush Pen

I drew these with a Pentel pocket brush pen that was running out of ink.  I like the texture the dry brush creates.  Because of that I have two of the pocket brush pens and I cycle putting new ink cartridges into each of them on a rotating basis so I always have one pen handy that is full of ink and one that is about ready to run out.  That way I can choose whatever type of line and texture I want to create on purpose rather than waiting for it.
