I was afraid of how the plain black and white sky would turn out but it's actually fine.
The black and white nighttime sky works fine.
Yes, I was relieved when I saw its finished look. It wasn't until the end that I could tell how it would come out.
I had drawn the stars in black on white and flipped the colours after scanning, so if it hadn't worked I wouldn't have known early on.
I'm really liking this comic. :)
