This my latest piece entitled "Fighting for Survival"  It is based off a photograph taken by Mark Bowman.  The link is here http://www.flickr.com/photos/mark_bowman/2600212692/
This is of two polar bears fighting in the water.  I love the action and dynamics of this composition.  It took my a while to complete, and the finished size is 9x12.  It is available for purchase.
I was so happy to be able to use this!
