Playing with light

After visiting the Hopper exhibition in Rome I've been playing with light. Trying to improve my skill at rendering light on and around different objects. 

I'm still painting pavements and walls, cracks and interstices, and trying to convey something of the alternative universes inherent in these spaces. Minute biomes (usually unobserved) but also the suggestion of something from the other side or some alternative dimension seeping through the cracks. 

I think Hoppers windows-into-rooms achieve a similar impact. The light pours into an interior (various settings) from the sunny outside.
