No, you're thinking of the Cinematics, where there are sight fornications of the eyes on some of the characters. If you look at the art of his characters in FFX, and the 3D models, you'll find that he didn't use the Japanese/anime styled artwork as he did for FFVII. FFVII was virtually the only one Tetsuya made that did have the anime feel.

Also, I would hardly call Akihiko Yoshida a more detailed, realistic character designer, as he did do the Character designs for FFT, TO, VS, etc. They are both excellent artists.
