Honestly, Dr. McCoy has always been my favorite of the trio. HOWEVER, Spock is by far the most 'fascinating' and most revered character of the series, I feel. He will be forever remembered and I love his phrase, "Live Long and Prosper."
This is a beautiful composition, something I would not have thought of. I love the minimum showing of Spock's face. The colors are beautiful. Love the blue highlights on Spock's hair and ear. Again, gorgeous colors and I love the idea of showing the galaxy! Wonderfully done.
