I did notice the logo and as you can tell for this one:

it looks like 4 people (like a conversation---or "coming together")

As you can see with the one on the right it does the something similar, but we felt it was something a bit more . And the one on the left, though nice, does not give the sense of multiple people coming together...which is the reason why this one (the one with 4 people coming together elegantly) is what became a finalist.

As far as plagiarism comment, I understand why some may say that because lets be honest...Without the FIRST ONEs (made by naufal), the this one would not exist.
However, the trouble with this...is that with naufal alone, this design woudnt have existed either. So what do we choose? Obviously the work of both of these people had a role in the creation of the logo.

So I'll gladly let you both share the rewards earned by the placement of this design.
