If you like to composite images, consider using the Earth as a component. Images of the Earth are available without charge online. You will find some websites that offer fairly high resolution files of the Earth, and once you have that it's a matter of selecting it from the background, copying that selection to the clipboard in Photoshop (Edit > copy), and then pasting it (Edit > paste) into the new environment.
The picture you see here is a combination of three photos: 1. The Earth, 2. an ice sculpture of a face that I commissioned, and 3. glitter sprinkled on black velvet fabric to look iike stars. I photographed the glitter with a star filter.
