Nomura's early designs are influenced by Yoshitaka Amano's ethereal style and manga art, exhibiting a blend of fantasy and realism.

Nomura develops his signature style with Final Fantasy VII, characterized by spiky hair, detailed clothing, and a blend of androgyny and strong personality. This is when his iconic look truly takes form.

Nomura experiments with more realistic character proportions and fashion in Final Fantasy VIII, moving towards a more mature and contemporary aesthetic.

Nomura blends his Final Fantasy style with Disney's animation aesthetic, creating a unique visual identity for the Kingdom Hearts series. The designs are cartoonish, vibrant and yet retain his signature look.

Nomura further refines his designs in Advent Children and later games, incorporating more intricate details, realistic textures, and a greater emphasis on fashion and accessories. His style becomes even more recognizable and distinct.

His work in series like Final Fantasy XIII, Final Fantasy XV, and the Final Fantasy VII Remake showcase a dedication to high-fidelity details and stylish aesthetics, blending modern fashion with fantasy elements.
