Awesome!

This is a very awesome doodle.
Firstly, I really like the pose of the hero and the way her cape and head thing are flowing, and the way the colour above her is almost 'burning', however the cape DOES look a little bit like an oversized piece of toilet paper got stuck, just because it seems really 'square' to me...
Anyways, the attention to detail on the beasts mouth, the teeth and form on its skull especially, and the character really do look good, but my only nag is that I wish that is was coloured, as the one tone makes the whole scene seem less spectacular...
All in all, its a good drawing but I can't decide... is she using the beast as a mount or about to execute some sick move to kill it?
