Feedback works best when it connects a visible issue to the viewer's task. General comments such as make it pop leave the designer guessing about the intended improvement.
Describe what is unclear
Say which element is hard to recognize and at what size. For example, the connector disappears when the image is reduced, or the label blends into the window behind it. These observations suggest testable changes.
Prioritize the revisions
Separate accuracy problems from preferences. A wrong model name should be corrected before debating a subtle background shade. Limit each round to the decisions that materially affect the message.
Confirm the revised result
Compare the new draft with the specific feedback, not only with your memory of the old one. Check that one fix has not created another problem, such as larger text covering the working hand. Keep a short approval note identifying the exact final file so the wrong draft is not uploaded accidentally.
