I'm hoping that you can upload a larger copy, but in the meanwhile I guess I'll dare to show what I've done with the small version. (I KNOW that as soon as I upload this, one of our good retouchers will upload their version and I'll have to sneak back and erase mine

)
I'm not good at even seeing the actual curve of his shoulder and arm around her shoulder, etc. -- so this can be done better by folks here who are good at restoration.
