Guitars and hands

This is a little different style than I normally post but I was lucky yesterday and got the chance to watch a good friend rehearse for an upcoming concert.... and I got this shot which I liked.

It was originally in colour but I wanted to try making it B&W....however, I wasnt able to quite get the contrast I was after...I upped contrast and clarity on LightRoom but is there anything else I can do? All suggestions VERY welcome :)
