Use the phrase "No suggestions"

[Musicgold]

Hi,

Is it correct to use the phrase 'no suggestions' in the following context.

Your report looks great ! No suggestions there.

Thanks,

MG.

Yes, but it is very casual of course, and it is a bit ambiguous: the reporter would have to understand that it is you that have no suggestions.

MM,

Thanks. How can I say it in a better way?

Also what is the formal way of saying that?

[Mister Micawber]

Your report looks great! I have no suggestions to make about it.

More formal and teacherly, perhaps:

Your report is excellent.
