I agree entirely: it's a lovely image. If I have one small criticism, it's that the road is a little too close to the bottom of the frame: maybe there was something unsightly on the other side.
You guessed right. There is a section of the slope from which I shot just below the horizontal tangent to the road. It is not unsightly, but I thought it would distract. One possibility is for me to caf (*) it.
