Draw a portrait by photo

I want to give a gift to my girlfriend. I have a photo together that we both really like. I want to order a portrait of this picture, but with minor changes.

In the picture we are on a regular city bench, and in the portrait I want to have a sunset and a sea behind. The store itself can also be changed to a more beautiful one. I trust your imagination completely. We must be recognizable in the portrait.

I'll pay for the portrait through the mail delivery service.
