The key visual shows graphic elements, but it also communicates an identity and tells a "story". That's why they usually have more dynamics than logos or other designs. Even if the key visuals look like posters or advertisements, they are an internal tool for the agency and should not be shown in public.
As a study project we were asked to create a keyvisual for a NIKE sneaker.

My areas of activity were:

Concept

Modelling & Texturing

Rendering

Compositing

University Project
