Really impressive that he stayed perfectly still except for his conducting wand! I like the intensity and gentle warning on his face and the pointing finger. Good focal length to keep the foreground from becoming too distracting. The only suggestion I might have is to crop out about an inch from the bottom - it is just dead space.
Having spent way too many hours in orchestra and band, this image really resonates (pun intended) with me. Although my initial reaction was the crop was all wrong, on further reflection, the crop is just right. This is the view I had of the orchestra leader most of the time. Thanks for taking me back to those long lost years. Absolutely a "10" in my book.
