With the way you drew her upper body so fluffy, it surprises me that you skipped out on the fur detailing on her butt and her lower left arm (from the elbow down).
While I absolutely LOVE this drawing, especially the panties tearing, I would have tried to draw the fur on her butt in relation to the panties on her.

This picture almost looks like she's pulling her panties up onto her (or had just recently done so), and if so, then I could see some of her fur resting just above the hemline of the panties around her butt.

Either way, I do think this is lovely, and I would love to get something like this sometime!

Lots to lurve... <333
