Anniversay Greenhouse Painting

The Request

Hello! My parents are married for 45 years next week and I want to surprise them with a edited version of their wedding picture. I can tip €10,- via Paypal. I’m thinking something like a painting.

I don’t mind if AI is being used. I’ve tried some styles myself, but the problem I keep facing is that they are turned into completely different persons. See here: https://drive.google.com/file/d/1xA6I6HSkq5TgAAobC8U28OdmroQtN1my/view?usp=sharing

It gives you an idea of a style that I like, but any other ideas are welcome as well. I will choose the best one.
Just keep in mind that the faces must match the original people.

Here is the original image of my parents with full resolution: https://drive.google.com/file/d/1m9iRrhzkRUW8qW8bYvAtI98G_ZUJuocz/view?usp=sharing

The Results

My watercolor style does not really match the reference image, which to me does not look like a watercolor, but I figured I would submit it anyway

Other Versions

Since the reference provided did not really look like a watercolor to me, I did an oil painting as well.
