Not bad at all. Maybe squat down and get different angles of them there to sort of show a sense of dominance or importance because they are in a band...a rock band especially. Let's take it to the next level...that's what I am challenging myself with too currently...you see what I mean? Yeah I can take a nice photograph, nice composition and all of that technical stuff...but now it's time to take it to the next level and generate new ideas instead of the cliche pics...ive seen this before. Like...in a few of my pics I've currently taken...I've seen it before...let's see new things.
It would of been cool to perhaps go beside the wall and get shots from the side and sort have them go down a row, seeing face to face down the line...if you see what I mean.
I looked at some of your work on flickr and they are pretty dang good...so that's why I am challenging you with that...overwhelm yourself with photos and researching to develop you style even more!! =)
