For an e-commerce 3D artist, portfolio proof is mainly an ownership decision. The page should make clear what this role approves, what it only prepares, and who receives the asset next.
For e-commerce 3D artist, keep the portfolio proof pass focused on problem statement, constraints and decisions, and before-and-after evidence. Make one controlled change at a time and retain enough evidence for another person to repeat the decision.
Show the problem, constraints, decisions, before-and-after evidence, and final result without exposing confidential source material. Apply this portfolio proof guidance to the actual e-commerce 3D artist delivery path.
