IMHO Rodrigo's design does better on contrast & rythm but there's a disconnection between related elements which can cause confusion. If I had to solve that I should try using a light background to enclose items that belong one with another.
I think that, regardless of the results I find this kind of exercise very useful. It's very hard for someone living in Argentina (or anywhere outside SF or NY) to be commissioned with a work of this caliber, so it's very ratifying to think "Could I do it better?" even if the answer is "No, I can't"
On a related note, is good to see Bowman work again after disappearing that many years inside Google.
