That is a very thoughtful message, Jim, and much appreciated.
The one thing I'd add is that the response "looks good" with no further comments almost invariably means that the person did not read what you wrote, in my experience. While I believe in being complimentary, I prefer details, especially when I'm circulating a rough draft for feedback.
This, by the way, is for an academic context. Around here, compliments on blades should be taken at face value
