I think that the symmetry would have better highlighted with some more triangular leaves and petals (If such thing exists).
I think that is borderline meeting the challenge due to the presence of the leaves. I found interesting that the triangles are decreasing in size as the image progresses to the right, I wonder if it would have been possible to continue this farther to smaller and smaller sizes that would have been another representation of a fractal. Although I am not sure how the image was done so this might not be possible, sadly the fractal properties tend to be more evident when there are many order of magnitudes between the larger and smaller length scales.
