Like the idea of the lily pad. Wonder if you could try two things:
1. Can you illustrate the lily pad or use a more stylized (less graphic) 2. What about incorporating the lily pad into the name itself...maybe negative (white) K over a green lily pad or outlined lily pad behind the K?
#49 - 4 lilypads forming an cross cloud. The four cutouts form a shining star, symbolizing success and correctness. #50 - lilypad with a negative space K
