I think the composition is actually more than fine. I would suggest try out dramatic lighting like in old (Disney) cartoons.
This is so good!

This is amazing! That rendering with the red lighting is perfect and breathes the approaching atmosphere of a demonic entity. One thing I would have added is softening some of the hard lines of the main character and adding some texture to his features and his coat.
