Star Wars looks okay, but these are such a hack job...I don't know, maybe I could get a job as a graphics designer at LFL because I can notice at least 5 things wrong with each cover from a design standpoint.
Star Wars
Tarkin is so damn blue that he blends in. (I know he was on the original poster, but not that bad)
The shot they chose for Leia is undynamic - it looks like she's posing with the blaster, not firing it.
Chewie has that "wait, where am I now?" look, which, I believe is a promo shot from Empire.
The Luke and Han shots aren't even from the film, take a look at their haircuts - this is small, but it bugs me.
WTF is that coming out of the end of Luke's blaster?
The big blue Photoshop glow...ugh. It's used to cover up bad work, like erase lines.
Empire
Vader looks like he's about to swat a Snow Speeder off of Han's shoulder
There's nothing interesting going on, on the cover.
The character shots they chose makes them all look bored. What are they all looking at?
Again, the purple flare around everyone is amateur.
If this was trying to re-create a poster, I don't know which one.
Although the Luke head shot is larger, the Han shot pops out more, leading the casual viewer to assume that this is Han's story, which it clearly is not.
Jedi
Look at all that empty space.
Although it does try to re-create the poster, the Leia slave girl shot is sort of out of place.
The cover is unbalanced - if you draw a line diagonally from top right to bottom left, the upper left portion is sparse and doesn;t have anything visually to balance the "shot" out.
What's Wicket doing between Han's legs?
Anyway, I'm being nitpicky, but these covers are quick, amateurish, and trust me, the artisans here have done way better.
