Do you just turn off the background when you take the printscreen? because here is another very gray background, and it doesn't fit at all.
Why do you have a roof? The roof looks kind of ugly. Just make each side of the map water like VTT usually did in his TW maps. It'll look much better than that very unnatural border and ceiling.
A little better with the smoke from the tanks. I'd still refer to Glory Hill, or almost any TW map for that matter. Most of them have smoke coming from somewhere..
I like your maps. They are very easy to comment on, aesthetically speaking, and they generally have decent, if not nice layouts. Sorry to be picky, but the waterways under the bridges look very unnatural with the very square bottoms. Make them somewhat shallower and make the ground look uneven.
With the lights in each cave, spread them out a bit. Maybe have them on every other support, or every third support. Putting them on every support is a bit excessive.
