Compare with the source
A beautiful scene can still show the wrong product. Keep the reference beside the generated image. Check silhouette, proportions, openings, caps, seams and fastenings. For jewellery, count visible settings where possible and examine chain construction rather than judging only the overall sparkle.
Read every visible label
Do not assume small text is correct because it looks plausible. Compare names, volume, logo spacing and other visible marks with the source. Where exact label reproduction is essential, plan for controlled compositing or retouching rather than trusting a generation to invent the missing detail.
Inspect the material
Metal needs coherent reflections; glass needs plausible edges and refraction; fabric needs a consistent weave and seam structure. Look at contact shadows and the point where an object meets a surface. These small transitions often reveal more than an overall impression.
Review the full campaign
Place the assets together. Check product scale, colour temperature, shadow direction and repeated details. A single image may work on its own but feel unrelated to the others. Confirm which variations are intentional and which need correction.
Finish with the delivery context
Review the actual exported size and crop. Check whether the product remains readable on a phone and whether text has sufficient space. Keep a record of what was approved. Clearly distinguish fictional campaign studies from faithful imagery of a real product, especially when building a portfolio.
