It doesn't matter which perspective you choose to write from. You're the author, so you can choose to give the readers any viewpoint you want. But whatever you choose, you do have to choose. Keep your perspective consistent, no matter what you do.
Uneven
I made one of my usual epically bad movie choices, just over the weekend. I thought it was going to be good because it looked romantic and it had an actress that I admire, but that's beside the point. The point is that the movie committed to a specific perspective from the first, and stuck with it through three-fourths of the film. There was a dedicated narrator, and everything. So imagine my shock and confusion when the perspective shifted, for just one scene, to someone else entirely. That's called uneven storytelling, and that's not the sort of thing I want to find in books.
