LOL! Those branches are fat! I noticed that the leaves are too few and too big, and that it still has the same looking shape as the default tree. Really mix it up in there! Play with everything but DON"T mess to much with the branches per segment option. You can move the first bar all the way to the right with little trouble, but to move the second is death! Also, try using stacked or staggered for the leaves. They are more natural looking than the default spiral configuration.
