To designer indsand: I love the subtlety of the musical note in #5 (the angle on the tree is too much) and I love the alpaca head silhouettes in #4. I would love to see a combination of these two. In #4 the strong black color is too much. If you look at the logos selected as examples by the customer, you can see that they might want a logo that's almost entirely composed of gradations of color without any strong black.
