I'd think natural tree growth could not be predicted, as every tree of the same species has it's own character, looks different.
What we see is supported by that which we cannot.
The top is drawn from what I believe to be a sycamore outside my apartment. A tree I will probably never see again when I soon move. Parts of the root are based off the Trinity Root sculpture by Steve Tobin in NYC, a cast of a sycamore that was hit with debris during 9-11.
