A Sketch in Blue on Yellow

I really enjoy this image, for a few reasons.  By pure accident it came out in the small dash/dot shading I use, and (as my sister would say, despite it actually not being) ironicly, I use that dash/dot shading most when drawing on small things, like post-it notes, which this resembles.
I always try to correct my sister when she tries to use the words of irony, ironic, etc.  It's actually ironic though, because one of her favorite movies is Reality Bites. which flat out states the definition of irony more than once.  And she can quote it, yet can't use the word right.
