The scene with Carol at her desk reminded me very closely of the scenes and animation of the character "Mirage" in The Incredibles.
No, the design styles are quite distinct. True, Carol's rather wasp-waisted like all Timm women, but Mirage was exaggeratedly skinny from neck to toe:

And the facial design was very different. Carol's face was a classic, characteristic Bruce Timm face; like I said, almost exactly like Timm's Lois Lane. There's nothing particularly Timm-esque about Teddy Newton's design of Mirage's face; they both represent similar ideals of feminine beauty, but the specific stylistic takes on that ideal are distinct to the artists.
Really? You can't see some similarity there and how Mr. Incredible was portrayed?
Well, some obvious generic similarities due to them both being caricatures of strongmen with disproportionately large upper torsos, but you can find thousands of cartoon characters designed along those lines, just as you can find thousands of cartoon women designed along the lines discussed above. And Mr. Incredible is, of course, significantly different because he's designed for most of the film as a middle-aged man who's put on a fair amount of weight; even after he gets back into fighting trim, he's still clearly got a lot of extra padding:

By contrast, this series' Hal is much sleeker and more angular, a man in his prime with no excess padding:

There's really no comparison. It's apples and celery. Bruce Timm's character design style is lean, sleek, and Art Deco; Teddy Newton's is softer and rounder. Also, there's more consistency to Timm's design style; it's caricatured, but he has a standardized, fairly uniform face and body type for male characters and another for female characters. But every one of Newton's character designs in
The Incredibles is more distinct and individualized, the caricatures taken to a more extreme level. We're talking about two very distinct design styles here.
I think the similarity you're seeing is only in execution, the fact that both productions are done in 3D computer animation. But even there, there are considerable differences in the level of detail and texture.
The Incredibles went to great lengths to give its caricatured people realistic skin, hair, and clothing texture, but everything in GL:TAS is more smooth and slick.
