Welcome! I suggest you find some good books on photography. Some suggestions are: The Creative Photographer by Andreas Feininger (actuelly, anything by Feininger is good IMHO), and The Book of Photography from National Geographic.
I know, I'm old, but I get far more from books than trying to...
Very sorry to hear about Lady Victoria. We become so attached to them - maybe more than some family members. We lost our Corgi, Ginger two months ago and still miss her very much.
Glad you have found a new puppy. She'll bring a lot of love to your life.
