COPICS
--These are Liquid based materials (mine use Alcohol)
--Seep into the paper, depositing pigment among the paper fibers.
--These blend via direct mixing.
--Tend to lay down color thick and evenly saturated, resulting in a nice flat look.

COLORED PENCILS
--These are Wax and Oil based materials.
--They rest on the top of the drawing, filling in the tooth of the page.
--They don't blend by mixing their pigments together, instead relying on visual blending.
--When laid down in a thick, solid layer, they look soft and deep.

If I'm extra stumped, I'll even do a digital composition study. 

Taking notes means that if I ever have to put the project down for a long time, I can pick it back up and not have to reverse engineer my own process.

Or if I ever need to write a tutorial it's (theoretically) possible to follow along.

Now that I'm warmed up, I'll get to work on the final image. Using what I've learned from the studies, I can make informed decisions about what colors I want to use on the final piece. So, even though I used Color X in practice, I know that Color Y will behave similarly and will look better.

I start by laying down the Copics. The even color layer will give an undertone to the colored pencils. This also helps me keep myself more or less on track with the coloring. 
I do use some blending in the copic layer, providing gradients between blocks of color. 
My mixed media method relies heavily on layering. I want to make sure that I have the copic colors where I want before I move on.

For the Colored pencil layer, I start by blocking in where the highlights and shadows will go. I also begin to add detail. 
With colored pencils, I take my time and layer the colors. Using a lot of pressure early on means that it's harder for me to add new colors later. 
As the layer of colored pencils builds up, I increase my pressure. On the final layers, I'm working on a very waxy surface now, so I have to press pretty hard.

As I work, I try to keep my palette as limited as possible. When using multiple mediums, color disharmony can get out of hand real fast. So I have a general rule that I'm only allowed to bring in new colors at the very start of the project and at the very end when I'm doing detailing.
