Painting Progression4 - Winter Really is a Blast!

In the final stage of this illustration, I add a sprig of holly to give it a Christmas feel, which is important for licensing.  I apply a glaze over the entire painting to unify all of the colours and to create a tonal cast upon which I will paint my final highlights.  The glaze is a weak mixture of ultramarine blue made extremely transparent by combining with a large proportion of mat acrylic medium.  I mix them together well, and then apply this evenly over the entire surface of the picture.  Once it is dry, I repaint some of the snowflakes and the highlights on the main subject with pure white to make them stand out.  A signature is added and the picture is finished.
