Drawing pictures that resemble humans

Q: I wanted to ask if all of the following are haraam:

1. Painting an impressionistic drawing of human, meaning a blurr or a silhouette to represent a human but not clearly painting the features.

2. Drawing a human figure with no face with the sole purpose of representing clothes.

3. Drawing cartoons with very unrealistic features for example a triangle for a nose and dots for eyes.

4. Drawing humans without a face.

Woman going for breast augmentation

Q: Does Islam allow a woman to do breast augmentation? I have been through a couple of articles on the internet which says you can, however it depends on your reason for wanting to increase the breast size.

My reason: I am really flat chested, my breasts never grew at all, not even after having two kids. I am married so I'm not doing this to beautify myself for other men, I just really feel uncomfortable and embarrassed and just want to increase my breast size a little so that it can look "normal".
