In trying to incorporate the feel of a guitar in a single picture, I came up with this.
I wanted the colourfull rosette around the soundhole to standout, so I made the rest black and white, with a touch of sepia look.
I have experimented with some HDR rendering, in an attempt to make the monochrome more defined. Have also tried to give it some punch with some dodging and burning.
All in all I think the result is satisfying.
