A print for my wall

I have images of two cities (my born city and my partner born city). I would like to fusion both photos side by side into one gorgeous composition. Then I will print it in a big landscape canvas and put it in a wall of the living room of our home. It will represent the union of our two born places and cultures.

Both photos have a different sky colour. If it is possible, I would like to fix that and looks more like the same sky. So that means that the images required to be modified.

This project is a surprise for my partner and our new home. That is why I want to have this work made it by a professional.

Note: the two images that I have have a good resolution:
Image 1 9000 x 3000
Image 2 5690 x 3201

If you would like to have a look of the images, please check the following link:
