Civil War Ghost Tale

Haven't named the concept yet, but it's one I've done a LOT of research for as my local area had some big Civil War battles nearby and it's been a topic of interest for me. 

Synopsis:  After dying in battle Billy, a former drummer boy for the Union Army, meets Jeb, a friendly ghost who helps him find his way home.  (More details to come as I figure out the plot and characters more)   

On the way, they have to fight off demons, other ghosts, and Devourers, corrupted souls of the damned who try and consume and corrupt other souls. 

I'll probably redesign the characters at some point, but for now these are the current designs. I might make human versions of them as well if I get the time.
