Could you provide some advice, suggestions, opinions with this project I've taken on?

I found myself in possession of about 25 pictures that were taken of a restaurant in 1976. That was the year the current owner, Dixie, and her husband, bought it. Dixie still owns it. She gave me the pictures to scan.
I scanned them and returned them yesterday, and took a minute to attempt to take similar pictures to do some comparing.
I’m doing some color correcting on the old pictures, using Word, and similar “correcting” on the new to make them match a little closer.
This is just being thrown together so I didn’t take the time to make sure the angles, etc., were just right, only similar. Also, the old camera took perfectly square pictures. I’m cropping the new pics to be similarly square, but of course that tends to cut out key elements that make the pictures comparable.

I’ve done one and two so far.

Two is driving me a little crazy because making it square cuts out one of the lights, which to me is an important feature. Also, the booths in 1976 were closer to the counter than the tables are today so squaring it up cuts out much of the tables.

Anyway, that’s just an idea of what I’m trying to do. Any suggestions will be welcome, even “Quit being so OCD about it all!”

Thanks in advance.
