That is pretty good Brian. From the low res I cannot see a join at all and the only give away of what you have done is some elements of symmetry in the clouds and a little in the ground. In some areas there is no symmetry at all and the mix of the two makes it interesting to look at.
Thanks Paul. I think I was able to get rid of the join. But, maybe on hi res some may be visible. I realized after I got out of PS that I hadn't done enough to rid the image of the symmetry in the clouds toward the center immediately above the hills.
