Could someone help me fix this photo?

Hi there,

I took this photo of my brother, with a disposal camera.

The only thing I've done is "Enhance" in iPhoto. I don't have any other editing tools, and I'd really love to make my brother more visible in this photo. Only about 3 pictures came out of that disposable alive, and this is one. The picture itself means a lot to me, and to see it clearly would be so appreciated.
