I love the atmosphere of this piece. You succeeded in adding a spooky supernatural vibe to the scene. It reminds me a little of Star Gate 1 the series where they reuse the Mount Cyanide Entrance not that this looks like that but the feel of it. The fact that at night an alien visitation could definitely happen. It would look like this from in the tunnel. Maybe not as many lights, but this is your piece. It WORKS!
Love the Volumetrics the use of the fog really helps the light from the saucer stand out. Plus I just saw a video on lighting and nice use of a Kelvin Lighting Scheme.
