I decided that I should share the pictures I took at each step of the process. I made the mistake this time of doing the black parts first. If you start with the lighter colors you get less bleeding from lighter markers picking up the darker colors.
I originally used the wrong red, it's way too bright.
It really blends into the orange/brown.
The colors don't actually have to be perfect, sometimes the contrast makes it work. That was the case with the two greens I used this time.
I don't know why my ability to take a clear photo took a shit on this one.
And this is the final product from my previous post.
Awesome I sure hope your students appreciate the effort :D
