Daniel Dociu has another high-profile project in addition to his work on Guild Wars 2: the cover of National Geographic. In this month's issue of the magazine, Dociu provides artwork to illustrate a "magical mystery treasure" of Anglo-Saxan origin that was recently found. Both the cover and the article piece show an era soldier with appropriate armor, clothing, and weapons.
Dociu currently holds the positions of both creative director and art director for Guild Wars 2. His skill and prestige certainly isn't hurting the game's profile any, as this achievement comes on top of the Exposé 9's Grand Master Award he won this past July.
The National Geographic issue is on news stands (or, to you whippersnappers, the "website") now.
