This is another piece of production art done for the ill-fated "Tiberium" game.
It shows the start of one of the game levels, an urban environment fortified against the harsh environmental conditions prevalent in the storyline.
The entire city is built on enormous platforms to protect the inhabitants from the invasive crystalline substance (Tiberium) that has spread throughout the region, ravaging the environment.
The large vehicle partly visible on the left of frame is an airship cargo vessel docked at this loading platform, while the structure ahead is a control tower and freight handling facility that you must pass through to enter the city beyond.
This is a full 3D scene that I rendered out and then retouched in Photoshop, adding elements such as the rain and some other details.
