This was a commission from a man who saw and really like what I did with the green Cygnarans. All of the freehand was requested, so none of it was entirely my idea.
I swear, Alister Caine is the warcaster that I've painted the most. The most recent version of him that I've done was a Classic Caine with a starscape freehanded on his coat. It works very well with the force that he's in, where all of the gun mages have some freehand on their greatcoats (the Black 13 have starscapes like this one).
