WHAT is Hawkgirl doing with her mouth there? It doesn't look like she's screaming or shouting - the rest of her face is too relaxed for that - but her mouth is too far open for a 'hmm, that's weird' sort of open-mouth look, or, for that matter, a cough or a sneeze (again, neither of which are likely given the rest of her face). I suppose she might be yawning...
