OCB - Character concepts

OCB is a (work in progress) comic, the full first chapter is available on my website / in the link.
These wore concepts to set the style for the comic, I hadn't thought of a scene, setting or story, all I wanted to do was storyboard fight scenes. The character on the right with the sword became the main character for the comic, I still haven't thought of names for them yet. The rings and patterns in the background were concepts for spell patterns that would illustrate a spell being cast or just magic in general use.
