Carbon paper experiments

Been wanting to try this for a while, but couldn't find my coloured carbon paper anywhere. Ended up ordering some dressmakers coloured carbon, which is good as it comes in fairly big sheets.
I was hoping to replicate or at least approximate the feel and texture of the lithographed book illustrations I make occasional posts on. These images have been tweaked a little once scanned (adjusting the black, white and grey levels), but I think with a bit more experimentation I might get somewhere near. Maybe playing with different papers and drawing instruments will bring up something interesting.

It's almost like coloured pencil, but somehow flatter and more primitive, which I guess if what I'm after. And of course there's no reason why I can't work over it with ink of whatever -
