To give your more specific suggestions, more information about your background is needed. You need to find evidence to prove your impact on your field and your influence on your peer researchers. You also need to find "comparative evidence" to prove that you are better than your peers with similar background. Recommendation letters alone are not enough.

I have helped lots of people here with their RFEs. Please search "fsa2000" in this forum and you will see many successful examples. If you have further questions, you may email me at: [e-mail] and I will help you analyze your case in more detail. Good luck to you.
