Found 2 more pieces of finalized concept art work about the 'net today for The Avengers film coming this May.
This first one is more like one we've seen already. More of a marketing type artwork.
This second one is a bit more SPOILER-IFIC so I'm going to code it. It's a partial look at allegedly
the finalized concept artwork for how the SHIELD Hellicarrier is going to look/operate during a sequence in the film.
They(Marvel) still tried to mask certain things hence the "looking through slated blinds" appearance.
That first panel is pre-action imo.
The second panel is mid-action as the Helicarrier goes from static to active mode.
The third panel feels more like you're looking up at the underside of it.
The fourth, still underneath, seems to show a partial backside look at it as it's moving away.
