Sacha North - Thesis color explorations

Here are some concepts I've been exploring with the main character I created for my Thesis. Its really fun to explore a little bit of color in Photoshop and come up with a color scheme. I did two different skin and hair color schemes. I'm kinda diggin the blonde with the blue and red costume, but who knows I may change it again!  The protagonist is a free-spirited orphan girl named Sacha North.
