This is my Uncle Geoff playing his melodeon in The Black Horse pub in Shipston on Stour at the Celts in the Cotswolds folk festival. I know You can't see much of the instrument but it was more the concentration on his face that was the point.
Technically I like the image, but without the instrument, honestly, he looks like he's asleep! I think the instrument would make the composition, especially if you caught blurred hands or something to communicate action.
