Hi!
Good job with your shoot, and good luck with the learning process. Think you're overwhelmed now? There is so much to know! I don't know a drop in the bucket yet.
One thing that I might add, though, is about bright backgrounds and shaded subjects. Usually your eye will go to bright spots in a picture first, so if there is a large difference then it takes attention away from the subject. If both your background and subject are in light shade, your exposure will be more even. Big Mike is definitely right about fill light, too...and when you see it for the first time, it's almost like magic.
Get your daughter to stand a few feet away from a light source. Look at the shadows on the other side of her face. Get a white piece of paper (or posterboard if you have it) and hold it next to the side of her face with shadow. Play with the angle of it until you see the shadows lighten. There's fill light! Bigger reflectors mean more light, and different surfaces reflect light differently. Something white will have a softer light than something silver, and something gold will have warm tones. Also, if you use black, you get the opposite effect...the shadows get darker.
Have fun!
