First gals torso and arms seem a bit too long, or else her legs are a bit too short. Theres the whole overusedness of the 'elemental' idea, but why even bother telling you to do something about it... Errm, lets see. Oh, well, the Electricity chicks pose couldnt be maintained. Her center of mass is not inline with whats supporting her, and she would therefore fall. Her weapons are pointing upwards, but since its on a string it would fall towards the earth, wich makes me think that you may have just switched a pose upside down? Just conjecture. Her legs are too short as well. Good work.
