Peter Schouten is one of my absolute favorite wildlife/paleoart illustrators. The level of detail he puts into his work is amazing, the foliage is lush and beautiful, and the animals are lively and compelling.
Dragon I drew while stuck in my booth at C3 this year. 11" x 14", graphite and white pencil on toned paper. The original was donated to this year's charity auction at C3, let me know if there's any interest in prints and I'll piece my high resolution scans together.
