In fact I consider myself satisfied with what Doutzen has conquered over the years, but we as a fan always want more... I don't think she has a good amount of shows and so many iconic moments at runway, especially between 2008 and 2009 but water under the bridge don't move mills. Campaigns I think she could have a lot more and especially of bigger brands. And Jessica Stam was #4 on models.com and look at her history, she has big 4, several campaigns for big brands (Prada, Dior, D&G, Armani, LV), although nowadays not having the same as Doutzen has... The only thing that Doutzen has remained excellent is in covers of the Vogues, which since 2005 she has never been a year without. But I think the brands/magazines usually choose her more for jobs in the summer season because she is sexy and combine more!
About Steven Klein, I don't know what to say. But anything can happen, especially if she's chosen by Tom Ford!
Like I said, let's see what happens... We still have another 10 months for her to have a good year!
