Looks fantastic. The art style is very retro and definitely Barksian, and folks working on the show say that Carl Barks and Don Rosa volumes populate the show's writing room, with several 'dog-eared' copies of Rosa's The Life and Times of Scrooge McDuck present. An example of this fidelity (besides the now comics-accurate red coat for Scrooge): the logo for the Junior Woodchucks Guidebook and Reservoir of Inexhaustible Knowledge is straight outta the comics - the Junior Woodchucks of the World acronym that, upside down, looks like an image of the Egyptian god Thoth.
Of course, not everything is comics accurate: Launchpad and Webby were characters unique to DuckTales, and both look great. Launchpad was a great character anyway (even Rosa, who's called DuckTales a 'counterfeit' version of Uncle Scrooge, likes him!), but Webby was a very annoying character it looks like they've improved substantially by making her an equal to the boys instead of a babyish tagalong. Huey, Dewey, and Louie all look to have separate personalities, too, whereas in the comics the act as a single character, often finishing each other's sentences or speaking in unison like the Shobojin. I understand that works easier on the page.
