I promise, I checked the white balance when I photographed this. And it's still yellow!
I dug this out today after working on a new painting during the morning. I began adding the strands of circular marks right before I quit for the day. My last few drawings were too light. And here I am really trying to develop some good darks as well as some subtlety and depth in the darker values. But I am as of yet unsatisfied with the black color I get once the India ink dries.
