The expression on the singer's face is very fitting for the live music theme. The mic stuff is distracting, but some is necessary so we know what she's doing. You might play around with making the photo narrower, or possibly cropping to just the face and a little bit of the mic. Having said that, the outfit does to the simplicity/mellowness of the singer's passion.
You captured the moment! You'll have to thank Jessica, for wearing such a nice color pallet and pat yourself on the back for a great photo! I'm picking up a little extra colour on her arms... maybe green? Anyway, I like it... Congratulations on a nice photo!
So difficult to get good gig photos when the sun is casting a shadow with a baseball cap. It's rarely effective to include half a hand at the edge of a shot. I'd have changed my position and tried to get more of her eyes. Ideally I'd have waited for her to look in a different direction, maybe inbetween songs so the sun didn't cast a shadow in her eyes.
