Help! Some tips about cancer awareness website

Hi all, I’m currenly working on a school project for which we had to choose a CNN Hero and create a website.

I chose Jonny Immerman a former cancer fighter that helps people currently suffering from the disease.
In his honer I created a website:

Jonny Imerman

I would really appreciate any tips you can give about:

  • reaching higher usability levels for the design
  • the layout of the pictures
  • any other elements you think should be changed.

Any help is welcome.
Thank you in advance!

Best regards,
