Got the idea from what the brief said about a blob. In these, the initials are in blob-like shapes, with transparencies so the overlap creates a third color.
I like your concept for sure. I think at first glance that the letters look like balloon letters. Know what I mean? I like the transparency idea, I think if you go down that road more (and I'd like to see it) try some more primary colors without it looking like the NBC logo. Keep it up!
