Alternate art for Kobayashi Maru

Doug Drexler has posted on his blog a variant of his artwork for the cover of the Enterprise novel Kobayashi Maru:

I think this might be the first time this art has been seen in colour; a black and white version was released in early solicitations for the book.

Drexler has also posted his cover art, without the titles, for the more recent/forthcoming books, To Brave the Storm, and Storming Heaven. Both of which were apparently inspired by Frank McCarthy movie posters. Go have a looksie.
