Star Trek Sci-Fi Themed Series of Illustrations

I just finished a rough sketch for one of the pieces in my sic-fi series. This one's obviously about the original Star Trek and it follows the piece I did on Doctor Who. Blade Runner is the next in this series, but I have to do the finished color work on this one yet after I get all the kinks out in this rough. The next post will probably to showcase the finished piece for this.
