Two weeks ago I spent a week in the Uckermark (a wild region, north from Berlin). I had a lot of opportunities for sketching. There are many lakes around mostly with grebes, goldeneyes and swans. The first six sketches are sheets (30 x 30 cm) from my sketchbook. I used mainly a black ballpoint with colored pencils. The great crested grebe (with the whole reflection) is a huge (A2 = 42 x 60 cm) sketch with inkpen and pastels (Neopastel by Carandache). The wagtail (sized A4 = 29,7 x 21 cm) is with ballpoint and Neopastels.
