Soo...I tried out adobe illustrator, but it isn't really my kind of program...It's just too hard to make any kind of basic shape in it. Vectors are hard. It took me ages to just make this stupid egg.
Though looking at it now....it does look very clean.
Anyway, then I went back to paint.net...to draw some microbes, because I happened to be studying them at the moment.
Yeah those are endothelial cells at the bottom. And a macrophage trying to eat some of the invaders.
