The colour balance looks way off in both these Ant. I find there's two main things to watch for with HDR, a sort of grey veil on the image or parts of it, and halos developing along the skyline. You can see both in these shots. If you have several exposures try combing just two - one for the sky and one for the land, without the HDR, you may well get a better image.
I love Dovedale. Is this just down the valley from The Stepping Stones?
