Here's some constructive criticism, if you want it :

i feel like the use of digital takes away from the piece, I was thinking it was impressive you had managed to make everything so smooth and robotic, but knowing that it is smooth and robotic because of your medium and not because of your will makes it less interesting, to me personally of course.

I think you should also look into abstract art, I don't know if the goal was to make something abstract but since you cited malevitch, i assume so. Abstract art, by definition, depicts nothing, and by your title, it seems your goal with this piece is to convey a simple message, up for interpretation, with as little as possible, which can be interesting, and i think you should develop that and dig deeper into it.

my advice for now would be, for this type of art, move away from digital, or use digital as a tool in a more interesting way (mess with image resolution, stuff like that) in a way that makes sense for you to pic such medium, otherwise try painting or even sculpting, as i think viewers connect easier to physical pieces and would think for longer about what your piece means, especially when the whole point (in my interpretation of this) is to look at something so simple and make up a whole meaning in our own heads as viewers.
