Strip #851 was the first time I've ever drawn Kira with puppy dog eyes. She isn't in a "pleading for forgiveness" mode very often, obviously. More often, she's wanting someone else to plead for forgiveness.
I referenced photos of sad puppies in an attempt to get this right, but I don't think I did. I think she looks more like she's about to pass out. Anyway, after all these strips, that was the first time I'd ever attempted that sort of expression for her, which I thought was interesting. After 851 strips, you'd think that I would already have given her every possible facial expression. But no.
