I enjoy the piece, but it seems kind of unbalanced. Most of the image's dynamics are in the strong vertical of the glowing figure and the really strong diagonal below. It seems like the open space above the figures just hangs somewhat awkwardly.
It might be different with more content, or perhaps a different cropping. One of my impulses would be to pull in the right side, but you can't as is with the heavy floating figure... Could he have fit somewhere else?
oh my, your quantum front side bus has had a lot of burgers.....
I like it
Maybe just one way to push it further - the contrasts of the characters vary greatly and while it's good for focus going to the lass on her knee, I'm a stickler for consistency of shadow depth. It's probably just because I can't help but stick to the laws of physics when it comes to lighting. I'd have increased the contrast of the rim lighting on the foreground couple and deepened the background shadow, and increased the depth of shadow across the floor in the right side of the image.
