I'm not thrilled with my eucalyptus leaves, but it took me years before I liked my regular wedge brush leaves and flowers. I believe it is going to take some practice.  Nonetheless, I love the design and the concept.  I did the A on Arches and the L on Hahnemuhle watercolor paper.   I found Arches easier to work with, but I like how the leaves dried on the Hahnemuhle paper.  I thought the color of the leaves too uniform on the A so I added some flowers.
