Minor Project: Animal group coloured shadows test

To make my characters stand out from one another and making them look as if they're standing, I've made some colour tests which will act as shadows instead of the black tones. Using the colours based on one of my abstract sequences I've applied these onto the group as a test. Number 3 was the very first test I did recreating the cyan,magenta and yellow  colours. I like numbers 9 and 7.
