- Check the details: View text, faces, product labels, and edges at full size, and if there are issues, specifically describe what needs to be corrected.
- Compose for the final use: Choose the aspect ratio according to where it will be used, and leave space around the subject and text so it can be used for banners, posts, or product listings.
