Much better.
Although this is clearly an alternate, inferior version of the poster actually. It took me a while to figure out whether it really was a different version or if I was just imagining things, but the painting isn't quite as good in some parts in this version, suggesting that this is an early version before changes were made and certain parts of the poster fixed. I hope it's an earlier version - otherwise someone just did a really bad job of retouching it for no obvious reason! (Which might happen in Japan ...)
Most noticeably, Luke looks bad in this version. The low-resolution version shows a better likeness of Mark Hamill (low resolution as it is), whereas this one looks pudgy and bug-eyed.
There is less detail at the top of Bespin, it's just painted blue without any crystal lighting effects.
Lando was also repainted a bit, especially around the eyes, giving his expression more subtlety and definition.
The little "starburst" at top right is more awkwardly paintined in this version where in the other it forms a perfect circle and is yellower. The shadows at the bottom are also less defined, as are the shadows on Han's face.
It would be possible to Photoshop this version into something closer to the final version of the poster - it'd take some work and skill though.
It's excellent to have ANY version of this poster in high quality, many thanks. I'll do somethin' with it!
EDIT: Hey, an idea - does anyone have the photos that those painted images of Lando and Luke were based on? It would make good reference if I'm going to try and fix this poster.
