Masculine

The pose is forceful. Hands on the hips as if to challenge you. The shapes are all square, wide, and imposing. The clever use of clothes and pose allow the breasts to seem flat and the shoudlers wide, giving a more masculien appearance. The shadows allow the face to appear more "chizeled" and the gaze is dead on. It is not holding back.
Feminine

her expression also is staring into you, but it is more enticing. It's inviting and acknowledging rather than questioning you. Her outfit and hair are bouncy and light. The lips are full and feminine.
The background is equally feminine and clusters around the model. As if almost a symbol of female submission in opposition to the prior pic's male dominance. However, the attention is still focused on the model. She is not weak by ANY means.
