Image: Tall narrow portrait format image, roughly 3 units

Generated from: Tall narrow portrait format image, roughly 3 units wide by 4 units tall. A small underground mine chamber seen head-on, like a stage or alcove where a single character would stand: rough dark rock walls on the left and right, heavy timber support frame, a corrugated steel back wall with rivets, a bright dusty shaft of light falling from above onto the empty stone floor in the centre, faint coal dust in the beam. Dark desaturated steel-blue and slate palette, one warm amber lamp glow at the upper edge. Painted concept-art style, no text, no people, no characters, no props in the centre — the middle of the floor must stay empty. Dim and simple, this is a backdrop that a character model will be placed in front of.
