This is superb! I really like the way this image "feels." I'm really into book cover art (an under-appreciated medium) and I'd totally buy a book with this image on its cover. This is stunning, beautiful work. I like the inspiration behind it also.
I really like your work... Especially this one. I love stars, moon, planets... And this vision of the saturn is pretty gorgeous. Really. Nice contrast between dark and light. It's balanced and... Gaah, soo awesome! And composition... I cannot see his eyes, and that make me wondering about them. Why? How they look like? Thanks for your work. It's awesome.
