I, too, have been inspired by Harmy's despecs to create some cover art. These are the first movie covers I have put together, but I am enjoying it and think they are coming along well.
Like EyeShotFirst, I am using the older artwork (always my favorite), but with slightly different takes (framing, color balance, banners, etc.). I used color corrected lightsabers more accurate for the films. ROTJ was already done in the source image, and the SW77 one I did. All of the poster images came from the Hi-Res Cover Art thread, and the screenshots I took straight from Harmy's edits in VLC.
For the spines, I went more with a 2006 DVD look. You can't tell, but the sequels use a font called "Episode I" with "Depecialized Edition" below in the same typeface as on SW77.
They are not quite done, as I have to do the backs and write the copy for TESB and ROTJ and finish the specs, credits, and fine print for all three, but they should be finished soon.
As these are my first covers, feedback is appreciated.
