Tawny owl life drawing

After more than a year and when I heard that this day is going to be the warmest of the month , I went back to the Park , where I was lucky and glad to meet an old friend who led me to a "new " Owl in a "new" location. The guy here was very shy and as soon as someone came too close to his tree disappead in his hole. It took me almost the double time I usually need to finish the drawing, waiting for the owl to reappear. Drawn with various Sepia fineliners & Faber-Castell Pitt pens
