First of all, it's a constructive feedback. It sounds friendly ,relax and personable. Rather than being antagonistic, the person is showing that you recognize some good points too.
Let the other person know that the feedback person is empathetic, feel concern,but it's not pity or sympathy.
The suggestion is so clearly that you can know what the issues are and helpful to improve your work. Also the person is showing careless by looking forward to read your work again.
I feel that peer 3 feedback is very helpful and constructive feedback.
