I'll try to critique.
It's a bit dark, all over. That doesn't make it bad, but it's the first thing I notice. I also think the contrast is a bit high, there is some 'posterization' here and there.
The eye is a black spot. Kind of looks lifeless in a way, would be much better to have some kind of reflection and more detail in the eye.
As far as the texture, I'm not sure if it's adding anything to the photo. If you take a picture of a rock band, and you put some gritty texture over it, it fits the theme. I don't know if the texture you used here fits in this case.
Hope that helps, I know you must get tired of the bashing but at least you know to expect it by now.
