Hi, I'm Arthur J Dorety III, a multi-disciplinary artist who loves all the arts—especially visual, musical, and literature. I grew up curious about science, science fiction, and fantasy, with dinosaurs and prehistoric life fueling my art and inspiring my learning to draw. I continue to explore world-building for fantasy settings, map-making, and landscapes populated with villages, cities, and characters. Beyond art, I enjoy writing and collaborating on projects, and I have hands-on experience with live sound engineering and music performance. My professional path blends traditional drawing and digital tools (Vue, Poser, DAZ Studio, Photoshop, ZBrush, Blender) with a love for paleoart and storytelling.…Hi, I'm Arthur J Dorety III, a multi-disciplinary artist who loves all the arts—especially visual, musical, and literature.
