Wolf in Winter Step1

Have you seen "The Grey"? starring Liam Neeson
It was very inspiring but also very scarey.
These large wolves appear to thrive for winter and can be fierce but are also beautiful.
I have started this 8x10 painting with an undercoat on the wolf of sienna and burnt umber. I plan to build up the layers of fur and have the brown mix with blue and red to give my greys.
