Photoshop newbie!

so this is kind of the first time i'm really using Photoshop, i took some pathetic classes in school on it, learning the basics, but i still find it much more difficult than illustrator :P
here are some of the projects i had to make for my midterms:

collage about me... and everything i identify with i guess :D

this is a collage of a guy i took some pictures of to show the urban life in Peru

this is a metamorphosis of my sister into a fox..
