Kurt Huggins and Zelda Devon, collectively known as Teetering Bulb, are a an illustrator team living in Brooklyn. Their clients include Realms of Fantasy, Dover Publishing, Wizards of the Coast, Honest Tea and Tor.com.
They are also creators of webcomics; and Tor.com, home of Tor publishing (se my post on Tor.com) is hosting their short story webcomic, The Dreaded Question, as well as a new fantasy story King of an Endless Sky (image above, bottom), which has just started.
The latter, presumably because it only has two episodes, is still lacking page to page navigation. [Addendum: this has been addressed (see this post's comments), and the complete story is available from this page. As of this writing there are three pages, with new updates every Thursday.]
Their comics approach has a nice painted feeling, while still working within the traditional comics framework of color filled line drawings. Their illustration is more painterly, but still has a graphic, linear quality that gives it a particular visual charm.
Their blog features many of their works in various stages of creation, in addition to sketches, studies, anatomy drawings, and finished illustrations.
Their portfolio is basically a subset of blog posts, as are listings in the right hand column for sketchbooks and prints.
