In her defense, the artwork seems to have been already done when she came along. There was probably a shortlist of four or five pre-selected potentials, which she then chose from; given Lucasfilm's recent history I doubt any of them were the nice Drew Struzan's. Maybe they have to pay more royalties if they use Drew's. (Because, you know, George Billionaire Lucas is a bit strapped for cash these days--he can't even afford to restore the most popular film in history. Poor guy. I hope he makes it through the recession.)
