The second attempt was good.. The first design that you did was Okay but need's improvement. When yourre working with grunge You wanna make it Stand out more rather then Take a Grunge Brush and apply it all over the pictures face and change the color of the Brush.
Oh wow. The second picture looks particularly spine-chilling. I really like the way you did that. I like it better than the first one since it looks more naturally done. If you're aiming for a grunge effect, you totally nailed it on the second picture. ^__^
