I would give it a 6/10. The video looked cheap and her face looked the same in almost every shot of the video. But again, her guitar work..AMAZING and she did look more comfterable near the end of the video.
I've seen cheaper looking videos. I think the point here is to showcase Orianthi's focus on the guitar. She's all about that guitar and without it she'd be less amazing. Those skills are what got her where she is, and to not focus on that in the video would betray her roots. I think it was a cute video.
She is famous for her guitar skills not her vocals! When I heard her live performances I was so dissapointed.. She sounded like an cheaper out of tune version of clarkson... But still she is a very talented guitar player.
