I usually take my own pictures on real life (for example the sky when it looks pretty) or I create the pictures using a simple base picture. (Using a mixture of brushes and layers on SketchBook Pro (a drawing software)) Hope this helped
No, I taken a picture of the A380 in-flight on google images. I then used photoshop to cut around the image so there was no sky and I managed to edit the light exposures to make it look more cool. I now can use it as a sticker kind of thing on all my projects when I feel like I'd like to. Hope I helped
