Looks awesome, only thing I could see wrong with this is Using tech brushes with a smudged background(correct me if I am wrong, this is a smudged background right?) I guess it just might be personal taste but IMO it doesnt flow that well, because you got grunge, something that is very free and messed up, and then you got tech that is Straight Lines, and very exact, so ya, other than that the signatures is awesome, the Text matches and is put in good position, gj man.
