Copyright exists in a work as soon as it is created (so long as it is in a fixed tangible medium). In order to obtain additional protections, you can file it with the US Copyright Office for $35. Can I ask what you mean by "graphical creations"?
Also, are you intending to photograph your work in order to protect it? What exactly do you mean by "publicly available documents"?
