Decide what the character is doing
A virtual presenter can introduce a product, explain a verified feature or express a visual style. That is different from portraying a real customer who supposedly used the product. Define the role in the script before choosing a face or a voice.
Cast for the creative direction
Expression, posture, wardrobe and environment should belong to the same idea. Technical fashion may need crisp architectural light. Understated tailoring may suit a softer interior. Representation is part of casting: give every character a specific role and a believable presence, rather than treating appearance as decoration.
Keep claims grounded
Use facts supplied and approved by the brand. Do not script an invented personal result or suggest a fictional character is a real reviewer. Label synthetic talent clearly when presenting the work. Product demonstrations should accurately represent how the real product can be handled and used.
Review the interaction
Hands, jewellery, seams, contact points and changing expressions deserve a close look. When a complicated gesture repeatedly breaks the product, simplify the action or use a product-only shot. Natural movement matters more than a long list of effects.
Build consistency across the set
Keep a character reference, wardrobe reference and lighting direction. Compare frames together before animation. A coherent character should remain recognizable across approved assets, while still allowing natural changes in expression. The goal is a useful campaign character, not an imitation of a specific real person.
Put the method to work: read the Creative Playbook or discuss a project.
