I like the touch of fantasy in the picture and how the building seems like a castle. The building looks massive because of the small men/women at the gate. I like how the bridge seems to be the only thing connecting the castle to the outside world.
This piece puts me in mind of the Kalb's dark warriors, tormented by their own souls, gathering in the shadow world, awaiting his command. (The LightBridge Legacy Book III) ✦✥✦ Art credit (?): Assassin's creed artwork - Killer by Yuan
