First off, I'm pretty sure I have that exact texture you have on that piece
My Opinion: I am not a fan of the text behind the subject when most of it is unreadable. Like I have no idea who the subject is and not being able to read his name doesn't help. I also find it a bit on the dark side, it feels liek we're looking at him through a really dusty window. Other than that it's not bad at all. I think a couple of minor improvements will help.
Those are my 2 cents. I could give you an hands on example like I did with Nemesis' Kofi/Spiderman piece, but I don't know who that guy is
