I really like this! You're an awesome painter, and that dragon head is phenomenal. Slight nitpick though, her legs are super awkward to look at. Maybe you were going for the comic book "boobs and butt" pose? I'm not sure. (Though I suppose in this case it would be boobs and hip/thigh, but I digress.)

Anyway, I feel like maybe giving her a more assertive pose would make this a whole lot more powerful. She just killed a dragon! That's fucking awesome! It would be great if we could see the victory in her expression and pose, and I feel like it would fit the quote you put in your description. She's a badass, pose her like one!

This is pretty cool.
