CGI: Mimicking SEM of a pluripotent stem cell from macrophage

I made mimic picture for amoeba-shaped object on SEM, by Blender.
The challenges here were fresnel material, blob particles on the surface, and ivy growing from the body to the floor.

This is the material node that is mainly for roughness on the surface and fresnel on the edge.

From other angles:

There are still uncompleted tasks.

For example, I wanted the blisters to be less saturated but they are more dark than other.
I wanted to make the ivy grow from the body, but the ivy and body look separated each other a little bit.
And I think the post-processing has more to do for SEM-looking images.
