Nice pic! She's like a paladin come to smite the undead! The golden hair and halo of the sun alludes to the D&D god Pelor. Although she has one of the most intense expressions I've ever seen on her face! She looks rather fanatical!
Of course, a long day of dealing with zombies and skeletons might do that!
The horse looks as intense as its rider.
Also, speaking of skeletons, it is an interesting view of the undead in the foreground, seeing his armor, largely intact, but the back of the head and spine visibly bare, with only a skull with rotting strips and bare spine supporting all that!
