Interesting.
I like the style of characters in this piece, they all look very unique. My favorite is the guy on the far right, his nose looks like a sock, haha. I would have preferred to see some more color, but if that was the mood you were going for, than I'm all for it. Not sure what you were aiming for in this piece, but I get a feeling like I'm looking at a movie poster for a science fiction film when I see it. Overall, I like the creatvity. Keep up the good work.
