Very nice represntation of sound. It could have been improved more had someone been playing it.
Over all the focus and dof are good on this only thing that is slightly off is your lighting it just gets to dark on the right side. Also had you been able to cut back the lighting glare on the harmonica itself it would have helped.
It took me quite some time to realize this was a harmonica, and I'm still not sure I'm right. Maybe it's the angle, maybe the lighting, maybe a bit of both. It being unclear to me de-emphasized the impact of topic.
my eye seems be drawn away from the sound of this to the bottom right due to the shine, maybe shooting this slightly lower to get more of the mouth piece in and less shine would have got you an 8 off me but due to the shine 6 - 7
