Three portrait photos, please suggest ;)

Hi.

I'm a beginner in the portrait photos, I suggest you tell me what changed in the three images that will display.
Thanks people!
Cheers

#1 - Very nice use of interesting lines and curves in the pose. Try to avoid clipping off the fingers. Be mindful of the wardrobe, as it would have been better to conceal the black bra straps.

#2 - Try to have a bare armpit aimed away from the lens.

#3 - In this type of pose, try having the model rotate her hips slightly so that she has her weight on the hip rather than flat on her bottom. Having the forward leg crossing in front of the camera gives it a larger than desired proportion. Perhaps having her left leg cross over will reduce this effect. Be mindful of your background and expose accordingly. If you have a flat, featureless sky, try composing your shot so that it is not included in the frame.

You and your models are on the right track, keep at it with more practice. Thanks for sharing.

Thanks, I fully agree with your suggestions. only one thing, at # 3 on the sky which believes it should do? not clear for me...
