The movie starts after a scene in space which is why you see a panaroma graphic a starlit sky is what you see in the background on the sides of the pic.
Other than that,
The sky background is a background made by me. Its really easy to do in paintshop pro. using the add/remove noise option and a bit more tweeking with blend modes and airbrushes. You can do the same to make a stardust galaxy, etc. Then I created another layer and drew the girl and the ocean as best as I could ^^;
The same can be said for the planet, several tools make making a planet easier, I'm sure there are plenty of tutorials out there without me needing to go into detail -_-; but if you'd like to know how just PM me instead of cluttering up this thread ^^
