Kamikaze is kind of unique in that it's made by a three person team - myself, my husband Alan, and our partner Havana.
We start our...frankly ridiculously long process by writing everything out in full on TV script format (it's just how I usually work when writing). We use Celtx which is a wonderful program and totally free!
After the ENTIRE episode script is finished we begin with thumb nailing. Here Alan's breaking down pages into pages, and then those pages into panels. From there he starts thumbnailing everything out page by page. From here he creates the full size page rough layout and drawing.
And then Havana comes in to clean up his underdrawings. She makes sure everything is neat, tidy, and that all characters are on model, and their acting/expressions are pushed to the proper levels. Alan sort of sets our stage, while Havana makes sure our characters are really acting to make each panel pay off.
While that goes on Alan gets to work on our backgrounds. If there's an enviornment that we need reference for (or that we'll be coming back to a lot) he'll build up entire models in SketchUp! This for example is our main antagonists, the Razor's, headquarters - and yeah...it's not very inconspicuous. For a reason, I promise. 
From there Alan takes a screen shot of the model and places it to match the character art in our scene. First he vectors...
Then greyscales the vectors...
As Alan does that I'm simultaniously going through the process of ink and paint. I begin by putting the clean art under a really obnoxious color and reducing it's opacity. This allows me to see what I'm doing with my anchor points a bit better. Due to our cell shaded and sort of 'animated' look, I don't get to do the wonderful inking I'd like to. I usually use a single weight line, but I have been known to vary that in the past - especially with forced perspective panels.
This is the clean work I start with..
and the inks I end up with!
From there it's pretty straight forward for me:
Flats...
Shades guides (used to keep my shades clean and crisp)...
And the final completed shading!
But sometimes...I get to do highlights and levels of interesting layered lighting, which looks like this!
Once my character work is inked and painted up pretty, Alan combines his finished colored and textured backgrounds with the final character art! During this process he'll add effects like dust, smoke or glows, and color treat the characters to further match the background.
Once the page art is done, it goes back into Havana's hands for lettering!
And then...we have the final page, all pretty and ready to post! 
It's a hell of a lot of work, but we think it's worth it!
