I have made another Google Doc, this time it compiles all of the X-Wing art and correlates each to it's LCG card. I believe that most (if not all) of the X-Wing art will be used for the LCG, since it must be the most expensive part of developing any card. Therefore, this file may very well whet your appetite, as it did mine.
Notice that FFG will sometimes zoom in on larger pieces, flip, rotate, and even re-color some of their pieces.
