Cleaned up the background to highlight the tree; simplified the foreground (no tiling) to show better the blood vessel cells. I’ll add more branches and some leaves, but I may skip the shadows. I want the cell photography to star.
Qutub Lab (http://www.qutublab.rice.edu/) has given permission to use their beautiful cell images in this artwork. I do so with gratitude for their generosity and in awe of their research efforts.
