First of all, both are awesome. The good demon boy with blue hair. Somebody that is both sweet and aggressive, driven but ethical. Ya know, assertive but not evil or a bully. The art style makes me think of a high quality teen titans, and I like the little quirks in the detail you gave hellboy. I like his smirk, his face makes him look younger (and a bit goat, cat and ape like, without going too far and still looking humanoid), and I kinda like his almost Batman like Utility belt. Yay.
