Of winter's lifeless world each tree,
Now seems a perfect part;
Yet each one holds summer's secret,
Deep down within its heart.
~Charles G. Stater
I started to think about hibernation, then about bears and other animals sleeping, then about winter 's desolation and cold colors... and this what I came up with. I wanted to accompany the illustration with a poem and I couldn't believe my luck when I found this one, which I think suits the image perfectly!
This is a modified version. I used a Photoshop filter called dry brush. I like the quality of the line and the contrast of the shapes which is accentuated by the dark contours.
