Matty, I did a quick job to see how it will turn out. I think we need a higher res, the faces are quite distorted when you zoom in. Here is a preview... I can get it much better, but if you could rescan at 300 dpi and email the photo to me, we will get a much better result. Don't try and post the photo here because it will be too big. I will send my email address on a personal message.
Regards, Peter.
