Marvel was playing with some pretty sweet concepts before they nailed down everything for The Avengers.
The Iron Man armor has gone through many iterations, but it was important that, for The Avengers, Tony Stark sport something really special. Likewise, if S.H.I.E.L.D. is going to have a helicarrier, it had better be the most boss helicarrier in the history of helicarriers.
With that in mind, concept artist Phil Saunders, went to town coming up with the best aesthetic for each that he could. No matter how talented someone is, though, nobody gets it perfect on the first try. Saunders gives some specific insight into the Iron Man armor along with art for various stages of development for the Helicarrier.
