No, it is not fortune telling. :P
In picture below is Zhi Lan Xiang Ping Jai Tou, spent leaves after god knows how many brews. As you can tell, leaves are uneven by shape, color and fermentation. Spent leaves show all the tell tail signs of quality.
A. Does not belong here, a much darker green leaf some how got into this bag. Most likely a Big Dark Leaf from a container next to the Zhi Lan Xiang fell over. It happens and often at tea shops or factories. As long as the ratio is low (usually only a few leaves), it does not make a difference.
B. Bruises, these are not fermentation color change. Bruises are created during fermentation process, tossing leaves too hard breaking leaves in the middle which cause fermentation in the middle of a leaf. A few of these in a cup will cause astringency.
C. Flower fragrance.
D. Light floral aroma.
E. Nectar/honey/fruit juice flavor.
