Hmm... getting better.
Try moving the two-rock arrangement on the left a bit to the right, and move the rightmost stone sorta in front of the other two. Make a mound so it looks like rocky hill/ peak with the substrate flat at all four edges. Just to see how it looks. It needs to look good from both sides.
Thank you for your tips. I just made the changes you suggested. What do you think of the big stone? Right now there is a part on the left of it that is hanging without substrate underneath. If I bury it a bit more it will be snug to the substrate, but I am trying to keep the height.
