One thing I noticed flipping back and forth between the TG image and the Vue image is that the water in the TG image appears to have less small noise in it's surface and lacks blurred reflection.  This gives the image a crisper look but is less realistic to my eye (although that may be because when I looked at the Mersey last Saturday it was choppy from the wind and messy from the heavy rain).

The other thing that strikes me is that I prefer your texture on the hills at lower altitude as it has more detail than the TG texture which is much of a muchness from top to bottom of the hills with only a small band of sand just at the water's edge.  The areas of grass on the TG texture seem larger to me and a slightly more vibrant green.  The vertical TG rock surfaces includes some sort of veins which may be in the model but I'm guessing it's the texture.  These give an appearance of fissures running up the rock's surface.
