[original post: The composition and use of the gradient in the background are great. The harshness of the highlight shapes isn't attractive to me, at least in this size. Overall a fine image. Good luck!]
Thanks everyone for the comments. Trubble was too cropped to leave much resolution, and then I gave it a bit too much in the contrast department. This is a straight capture, and a minor crop. Two softboxes, and a 40 degree grid shooting through a gel + barn doors. This is not a composite. The bubble just happened to separate itself from the heap - I don't know why, but it is why I liked this shot.
