Here is a polar bear I found in a zoo book. I sprayed light and dark blue acrylic paint on homemade white scratchboard. Then I used #11 Xacto blades and some steel wool to bring out the details. 6x9 inches (15.24x23cm).

A larger version can be found on my
ArtistPortfolio page.
Oh, did I mention
Blender is FREE? Previous listing.
