Added fire pits and made the bridge look more destroyed. I also changed the textures of all the primitive blocks, and made some minor tweaks to the map.

I added some pillars to make the bridge feel more fortified. I am keeping the pipes, because I think they are the best way to go. Man cannons make sound, which would alert everyone to your position if you were sneaking. I'm going for substance over stuffing.

You say aesthetics, I give crates. Presumably supplies like water and stored food. You say orc, I say pork. (Yes, I just made that pun.)
