I really like the design of the dragon. It looks very cute and contrasts well with the appearance of the enemy.

The composition helps to read the image in an interesting way. Given the order and color of the characters, you can't help but notice first the desperate dragon running and then the monster pursuing it.

The only thing that bothers me is the white background. I know that a simple one that complements the characters but doesn't distract from them would be hard to achieve, but I think you can manage it.

Cute! :з
