if yes, you shouldn't have the black outline, that you have on the walls, just on the first step. The others are placed under the wall level so there should be a black line to give the idea the stairs go down.
Finally did you try to add a shadow to the left wall? everything on the map has a shadow from left to right except that wall.
Oh, maybe a stupid question, that probably was already asked before....did you draw the knights on the walls or you took them somewhere on the web? It's like I have already see them somewhere, but maybe I'm wrong
