from the angle of the sword the front would reflect only sky, and the back would reflect only earth.
In the same vein, the armour is too thick to be worn, the gun doesn't exists and is technologically impossible. Also, the swords edge is too thick to cut. But hey, Fantasy, what are you going to do?
Looks good.
I really like the blending and the patterning on the cape. But IMO the earth/sky nmm looks too "comic book". I also feel the base is too "rough" and boscuring to the miniature, but that's just me.
