Good vs Evil - Librarian vs Sorcerer

With both of my Emerald Fist psykers finished I took a few 'action' shots with the two sworn enemies locked in a final battle pitting their powers against one another.  I like the contrast between the loyalist and his fallen comrade.

I haven't had a chance to play with either of these models but I'm going to force a list around both the next time I play either army so that they get their airtime.
