Thank you for the critiques and taking the time to respond. I was hoping for more from other people, but I'll take what I can get and will consider what you said.
Right now I am working on redesigning the guitar to something more organic and corpse-like. While I was initially fond of the contrast between organic object against an inorganic one, it isn't working as well as I thought it would. With the darker background added I'm also going to redefine the arms. While intentional blurriness may have worked with gray mist, it doesn't anymore with another layer of black added in.
