Awesome covers Harmy ! I'm nitpicking but I think it'd be better to use the stormtrooper's helmet for Star Wars and Vader for episode 6 because the stormtroopers are way more threatening in the first movie and Vader's role is more important in Jedi.
The problem with that is two fold. It was the most climatic scene in the first film and also Obi Wan is in the eye lenses. When I look at these covers what I see is that "they" are looking at. I think they are perfect. I do think the spine is a little crowded with the Despecialized edition on it as the top front has that already. But other than that I think they are the most original Star Wars covers I have ever seen.
