Unicorn sketch

I've been commissioned to paint a picture of an Unicorn for a friend.  I don't usually draw or paint unicorns. They're not part of my oeuvre.   But I try to break out of my patterns every so often, so that I don't become stale.  So here is my first sketch for this project.

It was drawn with pencil, inked and then colored with oil pastels.  Afterwards I tinted the whole thing with photoshop.
