KITH.me logo attempt #3

I got some feedback that the second logo attempt for my chat service Kith.me looked too childish, so I made a third version tonight that is more "serious" but is still more fun than my first logo attempt. I would much appreciate your honest opinion on my new logo suggestion :)

 Big version:

64*64 pixel version is the one that I will use the most, logo text must be readable even at this low resolution.
