Ahh...now that's lovely! I know that more often than not the whole b&w thing is more a matter of aesthetics and personal taste, but personally I think the color version here is much nicer. The colors are subtle and soft, but significant. I do agree with UncleSteve that the art work itself does indeed have a very "organic" feel to it and it certainly works well with lighting and the space it's in...one might think it twas all by design (subtle pun intended).
Again, personal choice, but I really like the color shot much better, however in either case, well done!
