This is just a little collage of things that revolve around the character on the left half of the screen, the one who was once a sea-dweller (His name is Vincent Eelwater, by the way). The boy in the lower right corner is his rival, Eros Phoenixfire. Oh, and this is important! The speaking parts are from a page, and Vince is speaking to his partner, not Eros. The little character standing is just a model for his clothes design (Disregard the face).
These characters are from my manga Dragonshadows. It's the story of a group of girls who have the ability to transform into different elemental dragons (Who are also known as 'Dragon Shadows'). The jobs of the boys is to protect their partner, as in their human form they're vulnerable, and need quite a bit of energy to sustain their dragon form. The souls of partner and dragon shadow are closely twined, so that if the dragon is killed by another of their kind (Which is the only way which they can be truly killed), they revert to their original form, or if their dragon shadow is killed by mortal hands, they fall under a deep slumber until their partner are reborn.
