As much as I love this, my friend, I still strongly feel that aspect of defence is weakly articulated in this piece! I see that dragon is shielding her from something that is falling above, but it just seems to me that she is not in a right place (not shielded enough by the body of the dragon, she is not bellow him, but lies near him hugging his head).
Perhaps you should play a little bit with composition and pose of a girl.
But still your colors and lighting are freaking amazing, no doubt about that!
