This is the work that has to be right. A memorial portrait is judged by people who knew the face, and they will know within a second whether it is them or someone who resembles them.
What decides it is almost never the artist's hand. It is the photograph you bring.
The sharpest, best lit one you have, sent as the original file. If the only photo is old and soft, bring several: sometimes a second photo supplies the detail the first one lost.
Yes, and often it is better. A three quarter view with real light on it carries more of a person than a flat passport photo.

Yes. The same rule applies: a sharp, well lit photograph of the animal, ideally at their eye level rather than looking down at them.
