local NGO
written on issues
NGO named? Provide the publication name and when it was published. Information like these needs to be specific for vetting reasons. It also increases your profile as a potential candidate. I caution you against just spicing up your presentation if you cannot support it. You may not be able to defend it later on.
formulate well informed and researched policies
Clarify if you are motivated to plana political future. your reference is implying such. Try not to over motivate your presentation. That could be just as bad as under-motivating your letter.
I am a good fit for this program
Take the opportunity to refer to your talents and skills that you can bring to the program. How are you motivated to share what you know and why. It should not always be self-centric, be open to representing your country overseas as well.
