If you want to get more realistic/fancier effects; try this.
Make a copy of your skin, hide the infotags, flatten it, make a square out of it, spherize it, save it as a jpeg (usually at 256x256) you can now use that image in most paint/model programs as a light map/light source.
You are now as good at making lightmaps as anyone, hehe.It is good and common practice to use items that would be reflected in real life also.(skies,lights,buildings,etc.)
That is all any environment map is, unless you want real=time mapping.If it was a 3d environment you'd make 6 of them in a set.
Nothing looks better than home-cooked reflections of your real skin...
