Inside the brain

I have become very interested in the drawings of Camillo Golgi. He was working in 1875 when he did a drawing of a dogs olfactory bulb, using his new method of staining tissue.This study of nervous tissue marks the beginning of modern neuroscience. The original drawing Golgi did is so complex, I had to break it down and put less information on a larger drawing. This is just the beginning of the drawing and I have done 4 different layers so far. The first is the pen and ink marks on paper , the next is the matte medium painted over the ink marks. The third is a thin wash of yellow acrylic and the last a thin wash of magenta acrylic. Now what to do next? I have done 8 of these large scale drawings.
