7/10 I would crop in on all sides. Seeing the crowd thin out toward the back isn't exciting and the non-stage venue walls are distracting/unimportant. I'd say go B&W on this one. This would be an OK venue shot, but I wouldn't really use it to highlight the artist. The spotlight and sound mixing table on the right also detract for me. For me, crowd shots should make me feel like I'm involved with the crowd or the artist. This doesn't make me feel involved.
