What does it mean to be human? (Voight Kampff Test)

I have tried to capture the dramatic mood of this key scene, where the essence of what it means to be human is under analytic inspection. Intentionally, this painting offers two different perspectives at the same time: one of the characters and one of the machine. This allows the viewer to take an active part in the analysis, and see what Deckard sees. Comments are more than welcome!
