Great job, and use of the bright blue color. After seeing the water-droplet, we are moving away from that image, our current logo has a water drop and it too similar.

I really like that you put the "inc." in the letter I!
If the droplet in the "B" was black, and looked like oil... not sure if that is possible.

Boss does not like the teal or light blue, not masculine enough for him, but we like the wave-like effect.
