Trenches to have wooden plank floors everywhere, along with retaining walls, but you’ve certainly got the right atmosphere going.
though it may not be 100% accurate I recommend making the grass more dead-looking (color-wise), I would also increase fog and increase the rain transparency. A bit of contrast (Color correction) may help pull the scene together alongside the other recommendations
