Shakira isn't that beautiful really! But I'll give you the other two
I think it is quite pretty. Okay, so it's not exactly a Lotus 72, a McLaren MP4/5 or a Jordan J191, but the general proportions are nice (front wing apart), it's sleek (rather than a box of messy, useless bits a la 2007/8), and it looks like it's going fast even when it isn't (a good trait - Concordes, Spitfires, Miuras etc all shared the same thing).
Edit: I can't see much of the Williams nose to comment. No worse than the Platypus Red Bull nose, surely?
