This the cover I recently completed for Mark Millar's new book for Image Comics "Starlight". You can read the article over at Comic Book Resources, including some very nice words from Mr. Millar himself. For those interested, the art is acrylics on 15 x 20 bristol. The book has a June release.
And here is the sketch for the cover done with pencil crayon on grey paper. You can see the costume changed a little from first to final version.
