Getting feedback from smart and trustworthy people can be invaluable. However, sometimes you may not agree with the feedback. This can be because you are too emotional and close to your work therefore not objective or your gut feeling tells you to ignore the feedback.
So how does one know when to go with the feedback and when to listen to the gut feeling? There is no formula for this except you will know when you feel strongly from within to ignore the feedback. Taking a second opinion from another trusted source can also help. However, if you are still not sure then go with your gut feeling.
The key, however, will always be to balance between being objective to the feedback and listening to your gut feeling.
