Originally from Greece, Paschalis Dougalis is an artist and wildlife illustrator currently based in Munich, Germany.
Douglais has a special interest in birds, and owls in particular. He works in watercolor, gouache and acrylic for his finished pieces, and often works from life in zoos and parks, capturing animals in watercolor or pen, often Bic pens.
I particularly enjoy his drawings on toned paper in which he works out from the middle ground with both ink and white gel pens.
There is a brief interview with Douglais on Birdingmurcia.
