It's not just facial expression. Jessica has a great voice, but when she sings, you don't always feel that emotional connection between her and the song. Singing is an artform that allows you to pour your heart out to the world, and I get the feeling Jessica wants to do that, but I also feel she's holding back. The best music is music that just flows from a person's soul, and she hasn't tapped that yet. She's afraid to tap that vein and let it flow, but if/when she does, she's gonna be a success. But she has to make that connection. Right now she's too hung up on this rock chick persona, but what she doesn't/hasn't realized is for all the toughness the rocker chick's showed off stage, on stage they were pure emotion. Janis Joplin, Joan Jett, Hart, they were all bad ass women off stage, but on stage, they poured out their souls, and that's why people loved them.
