Heh, not really. It might now have shown much, but I tried making them true to their canon ethnic background. In the canon, Mari is half-Japanese/half-British, Shinji is Japanese, Asuka is mixed Japanese, German and American; and I suppose both Kaworu and Rei inhabit Japanese bodies. : p
If not by those flaws (big hips(Especially Asukas), Shinji muscles etc) it would be a very good art. I like the concept of grown characters. And their expressions are done extremely well. And, as somebody already mentioned, Rei looks especially good here.
