Chris Seaman is an illustrator working in the gaming industry. His fantasy-themed illustrations are highly rendered, but always keep a feeling of cartoony verve and springy stylization, and often contain fun little touches in the details.
Seaman works in acrylic. There are a couple of brief process videos on his website, where he also has both originals and prints for sale..
I particularly enjoy his take-offs on famous images. like Holbein’s portrait of Henry VIII, and J.C. Leyendecker’s Arrow Shirt ad (images above, bottom three).
