The charcoal texture on the line work works pretty well here, and the texture on ground and sky too... for the sky it's almost like a photo... is it? If not that's really impressive work. Forms are good, shading's good, the characters... look interesting. XD You have a fire glow and everything. Maybe some more shadow along walls (if it's not showing on characters it'd seem it should fall from the wall) and rocks, but overall looking good! Nice tribute.
