My rule when taking photos in general is to not limit yourself with rules.
Dont be afraid of shooting grainy photos. Dont be afraid of shooting out of focus photos. Dont be afraid of shooting motion blurred photos. Dont be afraid of lens flares
All these when combined with good facial expression and movements will make a very interesting composotion.
I never used manual anymore when I learned aperture priority is the easiest adn faastest mode. You only need to adjust iso and shutter speed.
