Vacant Stare

I was bored, looked for something to draw and came across a poster that my friend Nikki gave to me when I moved. This piece is not quite done yet. I am new to drawing and want to experiment with coloring/shading. Here is the orginal, and as time passes I would like to finish it up different ways and show you. Enjoy.<br />

Story: I believe that just as unicorns can purify water, they can purify dreams. The poster that my friend gave me is hanging over my bed's headboard. This unicorn has a vacant stare because it is judging dreams to make pure.
