Two steps to the left or right and this would've made a decent image. as it is, you totally obscure the subject with the mic. Additionally, the keyboard is slightly slanted to the right. This is an advanced challenge so you could've also clones out the person on the left of the image.
A great attempt at a frustrating shot. I have been shooting lots of bands lately and it is tough to take a none-flash shot indoors of a moving person. It is a shame you were not farther to the left to get the mic out of his face.
