When I first broke into comics, most comics had to be black and white pages, which were later colored by a colorist.
I begged to add a few painted panels in between, yet Editors discouraged having it.
Comics had to be 1) black and white, then colored, or 2) the whole book be a fully painted. Nothing in between.
By the time i created Maxx, i could do whatever i wanted. Fans seem to dig it too.
I dunno why more artists don't try it.
