well thought, not as nicely executed. It is hard to guess the colors.. although it doesnt really matter. Lighting could have been a bit more dramatic, considering tha fact that there are 'marbles' - great refractors - on the table:-)
For the life of me, I can't remember if these things have color, but I suspect they do. (Getting old is a pain.) This is an instance where I do think color might serve the shot better.
