I like the orange, naturally!
The silhouette is nice and I like the reflections of light on the right side of the guitar.
Over all it's a nice one. Only one thing is a bit bothering IMO. That hand look as if it's going to drop the guitar. It doesn't work with the title to well.
I think that a silhouette of you holding the guitar like you're actually playing it, could be more interesting.
Over all it's a nice take on the challenge.
I like the color and the gradient. I don't like the composition - a guitar just held out at arms length, straight down - the whole thing seems pointless, plus the guitar shape is distorted. I DO like the fabric and its texture.
I wonder if there is a way to get the sound hole and strings "lit up". Nice idea. I would like to see a version of this with the guitarist sitting and playing the instrument in silhouette.
