This is one of my all-time favorite shows; the style and animation are so freakin' good it makes me sketchbook cower in shame. I ahte to sound like an old codger (because I'm way too young to be crotchety), but I think there's something to be said for how amazing cartoons were before CGIs. I mean, all of the ships and equipment are SO BEAUTIFUL as traditional animation.
Its a great piece. I really love the expression and feel you gave to spike. I was wondering if you would consider cropping it more closely so (especially around the hair) to make it more of a dark picture. The white destroys the mood somewhat. It is about giving up
