Inspect at reading size
Identify the image's main forms without magnifying it. Ask whether the focal relationship remains clear in the format where the reader encounters it.
Look closer selectively
Study one region at a larger view. Decide what the additional detail contributes and whether it changes your first interpretation.
Compare a reduction
Make a small thumbnail of your own work or sketch its main values. Use the comparison to decide where detail supports the image and where it crowds the structure.
