I'd like to see something you could come up with using some slight variations on the leaf shape, maybe the deltoid leaf shape for example, or maybe even a mix of different shapes. and maybe increase the detail in the leaf itself showing some of the veins.
then slightly reduce the font size of the aac and increase the font size of the practice name.
i had another thought.... is there any way you could use the 3 leaves to form the letters A,A, and C ?? maybe you might find a leaf shape that would be recognized as the letters , i dont know just a thought
