There are some typos in your covers, Nick:
"thirty" is spelled incorrectly on the second line
"Though," should be something like "However," to be gramatically correct
"executive producer George Lucas", fourth line
"thirtieth", fifth line
comma after "Irvin Kershner", first line second paragraph.
Sorry to nitpick, but I do so because I love your covers and want to use them. :)
