I love her expression and her body language in the full-figure image. In a better, happier timeline where Six rejected the evil in her heart by pulling her savior up and away from the ledge (instead of betraying him like the cold-hearted psychopath she is), Six would've likely fallen very much in love with Mono. This image of her staring desirously towards Mono's direction perfectly encapsulates what could've been. It's beautiful.

Actually, this entire piece is beautiful but, something about the full-figure image is what makes it so striking.

Shadow six do be looking like a Mesugaki huh
