Sending an entire draft with any thoughts can produce broad comments that are difficult to use. The reviewer may focus on a detail while you are uncertain about the main argument.
Name the part you want reviewed and the question behind it. You might ask whether the request is understandable or whether an example fits the point. Include enough context for the person to judge it.
Say what stage it is at
Explain whether the draft is ready for detailed editing or still changing in structure. Ask when feedback would be practical for the reviewer and give a genuine deadline if one applies.
After receiving comments, identify what you will change and what needs clarification. You can ask about a specific comment without requiring the reviewer to repeat the whole review. Try the revision and compare it with the question you originally asked. Keep useful feedback with the work, subject to privacy requirements, so that the next similar task can benefit from what you learned.
