The dragon stone looks better.
Just an idea, if you move the white circled rock to the black circled area, and the red to the yellow spot pushing everything to the right, you can leave an empty space down by the wood base. It could look a lot better if that spot is empty and the left side build a terrace behind the upright sitting rock.
@Andrew T the rocks are not staying like this I have a lot more to play with just wanted to see how the colour looked with the wood and a lot of the lower area is going to be covered in 15 pots of various Anubias and buces with just Juncus Repens around the back of the wood for a grassy sway effect (hopefully )
Really like the way you have placed the Wood, and as anything playing with the rocks till you get it just right takes time.
Have you been to Bretby was pleasantly surprised with the scaping supplies there, but fish were awful.
