However, it's an isometric game and the models look different in-game. Creating perfect "first-person" models would have been pointless. Basically, female models are slimmer and have female hairstyles (the second row, the one in the middle has a ponytail). As usual, we are open for suggestions, of course.
Maybe you should try posting ingame screenshots of the models, but I doubt the women will look more female. The important matter is really distinction.
Look at Fallout, for instance. The sprites aren't very detailed. I just checked and one female sprite had basically a skin-coloured spot framed by some brown shape for a head. Yet all females are very recognizeable due to the distinctive differences from males.
Most men have a really big torso and a manly stance with the feet apart shoulder-wide and the hands hanging straight down. In contrast, the women usually have their feet close together and their arms aren't hanging down. Also, their torso, arms and legs are considerably slimmer, probably exaggerated.
In your shots, the female models differ mosly in the face - which doesn't really look very female to me - and the breasts - if you can see them, like on the dancer and female gladiator (barbarian?) - while the slimmer torso is very subtle. Also, arms and legs don't really look different from men. Make the arms and legs slimmer and shorter, and change their posture if possible.
I think it would be very much OK if all females are visibly smaller than men.
Oh, and I have to ask: Is the second model in the top row supposed to be a woman? Because it really looks more like an "oriental" man to me, but the face looks like the face on all the female models in the bottom row.
PS:
The "dancer" looks like she sports a six pack. That doesn't make her look any more feminine.
PPS: The first female model in the bottom row actually looks best, because she visibly differs from the male model next to her with his bulging muscles, mustache and many other details.
But then I look at the dancer and wonder if that is a woman or a man in drag.
