Those trees still look pretty far apart to me. Try to find a set that are a little closer together. With practice you will be better at eyeballing the distance, but I still use the 4-6 paces rule for confidence.
Alternatively, as others have said, you can raise the straps further up the tree. Even at the ideal 5 paces I still put my straps as high as I can reach. (tip toes)
