Opinions on my theme

I’m developing a theme for a client that is a non-profit organization that invests in developing countries.

currently the site is devoid of any relevent content and is hosted on free hosting I use for developement. The real site is soon-to-be launched.

I can be seen here

The client has requested a simple, clean design and I have tried to achieve this.
I feel that the theme is quite boring though, and although it will hopefully improve with proper content I would appreciate any suggestions or comments on how it might be made more interesting.

I look forward to your opinions
