The hand was moving when the photo was taken, and evidently the shutter speed was slow.
That kind of blur can't be repaired in PS unless there's another hand that can be used to
copy/paste over the hand and blend it in.
What I did was add a background under a Layer Mask and created a "hole" that cut away
some of the blur. It doesn't un-blur the hand, but it is some improvement. I also removed
the doorway parts in doing this. The background color on the left and the right
aren't as matched as I would like, but I had to grab a section and free transform it to fit
and that changes the color.
I didn't do anything to change the appearance of the subjects themselves.
I don't think they need any modification. I did try to burn the area of the
dress that's washed out from the light of the door, but there's nothing
there to expose more detail in the dress.
You may not like it, but I cropped the image in order to present a more
flattering view of your mother.
The problem with having someone else do your editing is that they
do it the way they think the image looks best, and that may not be
your opinion.
