I heard learning to paint in watercolor is a great way to exercise your brain into seeing and expressing colors(and not value). So as practice I made an illustrating a few OC's (original characters) 
This image shows Dia the male guardian figure and Glu(left) and Grav(right). I tried to capture the characters dynamic relationship. In both composition, gesture and color. Both of these girls give their guardian a hell of a time.
So far my experience with watercoloring can be summed up like this, "It's like trying to tame a river." (and it'd be easier if I used watercolor paper).
