The continuation of one of my rough sketches in Photoshop. The illustration is showing acute endocarditis infection of the valves of the heart by the bacteria Staphylococcus aureus, which results in the formation of vegetations. Vegetations are a mass of platelets, fibrin, microcolonies of microorganisms, and some inflammatory cells.

The illustration is not done yet. I am still deciding on coloration, and I need to work on adding  more value in some areas.
