I've noticed a convention of minimal cropping among artists' Moleskine scans. Most people leave the rounded corners of the book visible, if not the entire scanner lid. It's like you're supposed to exhibit the sketchbook itself as well as whatever you've drawn in it. Look, I use a Moleskine. Observe its trademark rounded corners. This is not just any drawing, this is a drawing in a Moleskine.
And now, after that slightly derisive rant, I'm going to proceed to do sort of the same thing. >_>
