One of the most common frustrations artists report is clients who request changes at the wrong stage - asking for colour adjustments during the sketch phase, or wanting to rethink the entire character design after final renders are complete.
This comparison table maps each production stage to what it means for you as a client.
| Stage | What the Artist Is Doing | When You Should Give Feedback |
| Brief Intake | Reviewing your reference materials and requirements | Clarify goals and constraints before work begins |
| Thumbnail Phase | Generating 6 to 12 rough directional sketches | Choose a direction - do not request detail changes yet |
| Rough Development | Refining the chosen direction with basic structure | Confirm proportions, composition, and overall feel |
| Line Art or Value Pass | Committing to shapes and tonal structure | Final check before colour - structural changes are still possible |
| Colour and Rendering | Applying colour, light, and texture | Minor colour adjustments only at this stage |
| Final Delivery | Exporting files in agreed formats | Confirm file specs match your production needs |
Most budget blowouts in concept art projects happen because clients did not know the thumbnail phase existed. Reviewing eight rough sketches for 20 minutes early on is far cheaper than requesting a redesign at the rendering stage.
Ask your artist to include stage milestones in the contract with defined approval points. This protects both sides.
