We looking a photographs, we made sure each tree was visible from the front.
It makes sense what you are saying, it would be be more realistic in philosophy if the tall tree was growing more vertically, however we were also trying to look at the generally aesthetics and design of the planting. We weren't trying to go for a 100% natural appearance, rather an appealing design and layout. I said before we still have to wire and trim the trees, and one of the plans was to wire the big tree to give it a more vertical bend. I will post pics when we have done it, but im not sure how long that will be.
