Could do with some details of the images. Do you still have them in Gimp as separate layers?
You might do it with a layer mask:
Two layers with a (white) layer mask added. https://i.imgur.com/Ntgbf3s.jpg
Apply a black to white gradient to the layer mask. Using Gimp 2.10 so adjustment is easier with an on canvas mid-point adjustment: https://i.imgur.com/EUNsVT8.jpg
But then you have to go in and paint in the foreground (buildings in this case, could be a person) to restore the opacity: https://i.imgur.com/9Oy72OG.jpg
