Bringing in lighting and smoke effects

I move on to the background, adding colour and refining the light source. Using a photograph I took as inspiration, I render the shaft of light using the Gradient tool and Airbrush to create the bright glow within the dark chamber. Particles floating in the air, smoke and mist add to the mood. I use my custom Clouds brush for the smoke. Additionally, I employ my Rocks brush to add texture to the Ouj ore.
