Color and Light - landscape and squirrel

I decided to start learning about color and light theory. Some time ago I bought a book named "Color and Light: A Guide for the Realist Painter" by James Gurney. Recently I also signed up for a course about traditional painting. In future I will of course show here my results :). For now here you have some speed-paintings where I tried to put into practice that what I've learned from the book.
