Very nice. Although this outpost is overrun by orcs, I like that it looks so comical and thus peaceful. The sleeping knight, an orc in the tree (almost flying) and all knights look away (coincidentally), and the line of orcs: for me they look like laughing about this scene. Great!
And as said above, the bridge and the leg-windows are very clever. The bridge, however, does'nt look very sturdy.
