Like the second and third, but I'm not too pleased with the Vagrant Story mockup as a whole.
The combination of pre-rendered background(screenshot? I don't know), the sprites, and the green highlighting makes the whole thing feel too disfunctional to me.
I doy like the sprites, though your skeletons seem to be missing the vertical piece of bone connectings ribs on their ribcage. I like how huge their heads appear in comparison to the hero; is this some sort of commentary on the intelligence of running off into stange castles to battle demon lords?
Small question on your commishioned piece of artwork, what was the company's name? Where would the company logo have been pasted onto it?
