Character exploration, Miltary Serviceman

This was a character/world exploration piece centered around the use of steam/rocket powered weaponry.
I settled on a world where people have built a society built around weaponry and machinery that utilizes a highly volatile and colorful mineral.
I was imagining a world that is very gray toned and barren, except for the smoke emanating from all the machinery and weapons is super saturated and makes for a nice contrast.
This character grew up in a poor mining town built alongside an oceanside quarry slope, before he joined the military effort.
