"yeah i know, that's not nice", lol, i see no one disagrees.

You should at least fix the perspective. The top of the glass is the horizon line, since the elipse is almost imperceptible. All the other recipients should finish on the same line - but if they have different heights their top should form an elipse, similar to the bottom ( but flipped and congruent with the perspective angle.
If that's too hard, make only one piece & work on the background- make it a lab or something.

Reaction: Horrifying. Critique: written above.

The "distortion" of the specimens and the illusion that they are in the glasses is very good. I do, however, see the edges of back glasses coming through front glasses, as if the liquid is transparent. If it is, then the transparency is not consistent. Specimens from back glasses would also show through front glasses, yes?

Very good - if macabre - idea.
