I thought Beatrix Farmer had a very funny concept.
I like this cover. It has potential for a Story hook or twenty.
I wish I could share your enthusiasm, but my critical eye only sees the rough bits, and the scanned art helps punch up the contrast, helping bring out Rojigo, as he almost disappears into the background on the printed cover.
I have to agree with you on the cover deal, as Rojigo looks like a koala here rather than a Feline due to the shading and the angle.
True, you could have used a slightly lighter fur color for this cover. He looks absolutely fascinated by Null-G.
