In this case, I think the original color shot you posted is the way to go since your work is colorful. I don't get the ladder, etc. If you are attempting to show us the piece of art, a more isolated shot with proper lighting would help the evaluation. Of course, I may have missed the point here. Wouldn't be the first time.
Color would tell more about the subjects, although I feel B&W helps with the integration of the layered figure. In this color photo, I have trouble with the yellow hanging figure behind the ladder not receding as I would prefer. The over layered rearrangement of the panels was an isolated shot, if not a properly lit one. A point, if not, "the" point, is trying to get the isolated shot to relate to a broader scene. The ladder was there and I thought it helped define space and I like ladders and can find them meaningful literally as well as symbolically [though that may just be me].
