From my comic: [link]
This is a larger version of a sketchbook entry and is shameless comedic fan service. More so than I intended, actually, because Grace is supposed to wear a black top under her sweater that should be covering up her chest a little bit more here and I apparently forgot to include it.
I considered correcting the mistake, but as I said, it's shameless comedic fan service, so it's actually sort of appropriate.
