Jack Lumi Concept Art Valhalla Comic

So I haven't posted anything dealing with my other comic book up here in awhile. As of today I decided to call it simply "Valhalla".  It was codenamed "Project Valhalla" and I've been mulling over ideas for the name for a long time now, and as of today I chose Valhalla.  Valhalla is the name of the planet that my other comic book takes place on.  It's a fantasy comic book and I plan on posting more about it soon.  It'll probably be up on my tumblr when I get around to it, but for now here's some concept art from it.
This is of the mage character Jack Lumi.  I'll post more about him at a later date.
Enjoy!
