The first image (below) is a picture of the Airbus A350 XWB. I have taken the image from google, removed the background and put a simple but sleek gradient on the back layer.

I then got an image of a sunset, and moved the Airbus Aircraft onto it. I have re-sized the aircraft.

Finally, I have made alot of adjustments in this image. I have rotated the aircraft to create the effect that the aircraft is flying into the shot. I have also added a few colour corrections and clouds. The clouds are just a simple image from google and edited to look part of the shot, I used the smudge tool on the edge of the clouds around the aircraft so it flows and looks realistic.
