Coloring Out of My Comfort Zone

My digital drawing professor and most esteemed drawing sensei is fond of having us color our self portraits in line when finished with them. Using a variety of Photoshop techniques on multiple layers we are encouraged to use run through techniques and experiment with different colors. I always find that I feel a little out of my element for this project, as I would far rather simply color them without the bells and whistles. Still, one does not study art to stay in one's comfort zone.
