I agree on Cap being the best (and most likely to 'work' of the two images); Thor's 'chainmail effect' outfit hasn't looked right from the start. But then who knows how it'll look on-screen?
The hammer actually looks pretty close to the comics, only the handle would maybe be a bit longer... I guess again that it'll come down to what looks good on-screen, though I'm not expecting the Thor film to be much cop at all unfortunately (I'd be happy to be proved wrong). For one thing, it'll struggle with the sub-Shakespearean dialogue unless the characters spend all their time not saying much, or are good enough actors to get away with it
