It's just one little detail, but I love how her tie is flopped over to the side like that.
Like, that's what would happen if someone was struggling in bondage. Hell, the kidnapper probably had to toss the tie off to the side of her shoulder like that in order to wrap the ropes around her chest and her arms. So many artists don't really bother with this kind of thing but I always enjoy seeing works from artists who do.
Very cute picture, super effective-looking bondage, the way the ropes are squeezing her arms like that is extremely satisfying. Her shoes look great, too.
