Photo Restoration

I've been trying my hand at restoring some old photos of my grandmother that my mother scanned and sent me.
before - there is an obvious bend mark near the middle of the picture.

After - I removed the line and cleaned up the picture a little. Unfortunately there was a lot of pixalization in the picture and I could not yet figure out how to remove it. I had a good bit of problems with the patterned dress on the girl on the far right. The dress was smudge and pixally so I didn't have a decent spot to pull from.
