I found this concept interesting, so I decided to try and some prospective; to try and make it read better as a space. I feel there are still some tweaks to be made, but for now this is my concept art for the cells. I have also been thinking about my approach for the white blood cell, after going back to my research I found that anti bodies block receptors on a virus. this causes a lost its ability to infect cells in a virus; it can then be easily destroyed by White blood cells. I have been thinking that the tower could send out antibodies, and also absorb viruses ( growing a tentacle that stretches and grabs the virus).
