#67 is very good looking, we like it, maybe if you can think of something that could be added to this one, try it, also can you please try different colors (not orange or purple, but some nice combination form the others).
#69 is ok, but it's still missing something, hard to say what, maybe some kind of merge with 67 come to my mind or the "o" should be more visible/louder/playful.
