Thanks for the comments Aloysius and Technik. It's interesting what you said about over sharpening, as I hadn't picked these as being oversharpened, can't see any sharpening haloes etc. Maybe it was just very good camera technique and a sturdy tripod.

The HDR technique I used to produce this image does utilise local rather than global contrast to give the images more punch and that does make them look quite sharp.
I did get some feedback from someone else about the 3rd one being a bit soft, so that's the other side of the equation.
To me it's all a learning experience. And how much and how little sharpening to use is an important factor. Thanks for bringing the point up.
Cheers
John
