Whats that thing in her hand? An cigarette? It's quite normal that bananas and
apples hang in the air without gravity, but I've never seen an robot smoking :-)
This is a comment for the sake of comment, nothing to crit here.
However, this is kind of work where 700 pxl is too limiting, I would say that most
of details cannot be seen at this size.
Hope that the exibition went okay and everything's sold out.

Great picture
