Logo re-design competition for "NBT" Network Broadcast Thailand

This is one of the biggest logo contest in Thailand right now. We have to re-design the logo for NBT, the government radio boardcast in Thailand.

They want the logo which is formal and international, has a Thai design and easy to remember. (ref: National Geographic, NBC, CBS)

My logo can be seen as a "N" for NBT and 'ท' for Thai :D 

NBT logo re-design by me:
