Good photo. Demonstrates sense of depth. Sure looks like an onion. Seems you did well.

Excellent image !!

Just one thought [aside from the interesting choice of colour] ...
As shown, all the cells appear to be cavities, but I presume you didn’t actually section them !

Would you agree with me, that it looks more realistic when rotated 180° ?

Did not change the color :)

Yes, looks more logical (like both of them, thanks !)

Excellent image, Saul
... looks like fungus, but I don’t know enough to identify it.

[ Aspergillus niger seems a likely candidate though ]

There's definitely a fungusamungus. Closer examination required. Is it capable of movement? That goes a long way toward identification.
