Color Keys Exercise!

Here are some color keys that I did to practice color and emotion in a story. This is part of a little project a did last year, so the story and characters are my creation as well.
I also take the opportunity to practice compostion.
I didn't know how much i should render or how precise the materials and perspective should be, so some frames are better than others. But no problem since the objetctive was to create a visual color guide for a imaginary animation short and the focus was emotion throught color.
