It's hard to say without seeing, what you're talking about. But the ripples and texturing may be from the installation. Could happen from over heating and/or over stretching the film. While the line across the hood, IS visible on my car. It's barely visible and disappears very quickly as you take a couple steps back. You can't even tell it's there at all on my front bumper since it goes to the edges. Which is something you could do on your hood if the edge bothers you that much.
As for the orange peel. The factory paint itself has orange peel. And unless you had your car wet sanded...you shouldn't really notice a difference on a quality installed bra.
I have 1/4 hood/fenders, full front bumper/lip, and side mirrors clear bra'd
