08 - the white colour is a little overpowering
06 - the colouring makes Brass's face look a bit unclear
05 - too much green colour and the colouring on Brass's face is too heavy/overwhelming
05. I think he's too far away, and the green colour is a bit overwhelming.
06. Too much green, and his eyes are really standing out, which makes him look a bit devil-ish.
08. The texture of the icon looks a bit weird, and maybe the text should've been moved down a bit (since it's right under his chin). I do like the font though.
