I've spent time reading over your draft genre pieces. Here are some general suggestions that will help strengthen your pieces:
1. Develop your headings and titles. A fully developed heading may be 2 - 3 sentences or more. A title is generally short -- but make the most of it. "Waris Dirie" or "Waris Dirie -- One Determined Woman" The 2nd title is stronger, yet it still doesn't "cost" that much. Agree?
2. Among your 5 pieces, include at least 3 pieces about specific events or moments in your biography. General pieces that give an overview of a person and that person's accomplishments can be useful, but don't stop there.
3. Aim for at least one piece from the point of view of a "contemporary" of your subject -- someone who knew your subject and had a relationship of some kind with him or her. That person undoubtedly had an opinion on your subject and a way of voicing that opinion.
