Very nice work
That circular light seems like it could have more of a glow from it just an idea, I love this one! It's perfect. It's well drawn. The lines and shapes are so sharp and clear. There's nothing sloppy at all about this piece. The shading and differing hues of gray really enhance the overall mood of the artwork. I think it works great as sci fi piece, at least that's what I think of when I see it. I really like it. Because of the dark it really makes the few spots that are blue stand out. Making them more noticeable.
