Drafts

 Coca Cola headquarters. I aimed for a relatively funky look, inspired by the company's "interactive beatbox building for the london olympics" (http://www.fastcocreate.com/1680340/coca-colas-interactive-beatbox-building-for-the-london-olympics)

 I naturally assume Facebook should have a more blocky, chunky and simple look to it.

 The bridge as inspired by the Helix Bridge in Singapore. (http://www.yoursingapore.com/content/traveller/en/browse/see-and-do/arts-and-entertainment/architecture/helix-bridge.html)
I especially liked the bridge's design, it gave me a sense of connectivity much like the concept of Coca Cola and Facebook.
