Yes, this is a composition from two pictures. I found the falling coins alone not too interesting, thus turned them to the left and added a hand, holding other coins. This gives an impression (at least to me) that the money "flies away" from the hand. Quite common feeling to me, especially around Christmas.
I think, my camera has a problem with the second-surtain flash sync., since at 1/30 the "tail" continued forward the coins. I retouched this at the very obvious places, but you can sill see this effect in the middle. Quite strange, I think. MCsaba
