shiny objects always present a challenge. it seems like this was a soft scan or maybe it was intentional. sharper is better for technical details of course. if you are having difficulties with the hot spots from shiny objects, they a spray powder ant-perspirant like right guard and dust the surface of the item then polish off parts you want selectively more shiny. for a less pronounced effect along the same lines, a can of hair spray works too. both of these clean up easily with a little alcohol on a cloth. for a more dynamic image try laying the instrument down and get close so your depth of field starts to soften the details as you get further from the focal point. or just have a prop that allows you to angle the instrument in the image like it is reclining and trying to relax. 8o)
This is a good choice of subject, but it appears rather static as presented, standing there centered in the frame. How about zooming in and featuring the wonderful complexity of the keys, metal rods and levers, etc; preferably at an angle. Zooming in on the keys would also make the range of tones (visual) more balanced: the extensive dark background casts a somber tone overall. Other ideas: Take the photo looking into the bell? Or with someone playing the instrument?
Scott, for me this image doesn't really jump. The lighting is not quite right, I can't tell you what is needed because I'm a novice with lighting. Trys a few different lighting setups and see what happens.
