A good attempt, but I feel the background is too close and the shadow much to sharp. Even though the light sources work together bringing out detail and nice colorurs it has this "placed on the table" feel to it. Perhaps also just a bit oversharpened? It's a nice object though and I'll give you a 6 for it.
The lighting could be much more interesting here. Seems like just a snapshot of a trumpet, the shadows are distracting. Also, the photo seems pretty grainy for such controlled conditions. Maybe a concious choice?
