So I am sharing all the layers, same pencils, etc. This is a throwback to a printmaking technique that I learned in college called lithography:
under this process, a person can create a complex composition by adding the colours in layers. IE first the yellow, then you ink the stone with that colour and run it through the paper, and wash, rinse, repeat for every colour, manipulating the stone so that the proper things are highlighted. The trick is to match the paper so that it all fits together. I am doing a crappy job of describing it, but what I'm basically doing is doing it a colour at a time, with the watercolour pencils, and having it all add up.

|Pink after Watercolour|
|Red before Watercolour|

|Blue + touchups (E brown, black, etc)|
