Kelly,
There's no real information in either your N+3 or N-5 exposure. What you do have there is a barely discernable texture which is just a transition from a textured shadow/highlight to a blown shadow/highlight.
If you look at the Zone Ruler you posted earlier, you can see that your real textures shadow is N-2 and your real textured highlight is N+2 which is a 5 stop (N-1, N-1, N, N+1, N+2 ) dynamic range. I say N-2 and N+2 are "real" textured zones because there is information in those zones that can convey a usable amount of detail and texture in an image. A 5 stop dynamic range is typical for a small 6 mp sensor.
