I'm not sure I like the fox one Nige, it looks false with shadows all over the picture on the rocks etc, but with no shadows around the fox. It would possibly look better in colour, as there is not the contrast around the fox I feel there should be.
Dont take this the wrong way, I am not trying to say it is false.
Its a little bit the same with the spaniel, it is backlit by the moon, but a complete lack of shadow.
Show us some more of your usual pics, which are very good!
