The medical animation effectively illustrates the basic movement of blood cell movement through a blood vessel. The 150-frame medical animation expertly depicts blood cell traversal within a blood vessel. The layers or collections are well structured, organized and labeled clearly. The movement of the red blood cells are controlled with a geometry node for easy editing, providing controls for cell count, vein radius, cell speed and rotation speed adjustment. The Blender scene file included a single camera and point light.
The most notable improvement could be a better choice of texture maps used for the vessel wall and blood cells. The texture maps seemed stretched and lacked defining roughness/height displacement. The same texture seemed have been used for both surfaces. The improvements would be separate textures with bump/height map, adjusting specular lighting on each surface and a lighting/render technique that mimics subsurface scattering, making the surface look more aqueous or translucent.
But overall a useful animation. Thank you.
