not sure on the engine air in-take, reminds me of older cars, ones with triangle in-takes...
the front wing is interesting, seems to have changed considerably since the first 09wing used in testing last year. looks better than the Renaults god awful triangle wedge of a wing (however they may prove me wrong).
the low (fat) nose is a change from the high thin one, similar to the Williams 09 car. i think the idea is to create a low pressure area under the nose, causing low drag down force.
the front wheel brake ducts seem to have a vertical plane, i'm guessing this produces a cleaner air flow in the ducts, to the radiator in-takes and bodywork. the radiator in-takes look heavily cut away.
also note, the car is white, this is because of the low wasp in-take, just like baby flamingos...
