Khan, the cover with Huma and the Minotaur is really sweet.
I like the amount of depth you go with Huma's pose, the sword, the shield, really feels like they are in actual space. My one nitpick (i'm allowed one <g>) is that the helmet looks, feels wafer thin, plastered against the skull... unlike the sketches that you did. A micrometer more thickenss on the helmet I tthink would have given it heft.
Love the design decision of havin the negative space echo of the helmet's wings echo'd in the Taur's Horns echo'd again in the sweep of the dragon's wings. Very nifty.
Great stuff, thanks for sharing.
