I wish I had some kind of art background, where I could intelligently comment on the juxtaposition of the characters and emotions, the play of light in the scene and dramatic shadows, the sense of an impending battle of epic proportions through stillness in the centre and blurred movement of the dragon's body. But I'm not an artist, so all I can say is, "wow, really awesome!" - I hope that will suffice.
Until now, I've never really thought about wanting to give a green reptilian-type creature a hug. You sir, have changed that. Now go get that big bully, Red.
