Aesthetic is very subjective, yes, not just that, I feel my own aesthetic changes according to my mood itself. Aesthetics is about how we think, see and feel too right, so I'm not sure why we're even trying to define it, since we can't describe what we feel sometimes either. Aesthetics can be in any form, shape and colour, it can be a forever mood or just something about the present. We see the same subject differently and feel differently about it.

Aesthetic doesn't need to defined. This poster too, has one same object (that is, the FISH) repeated in different directions and different ways and different styles along with different backgrounds, depicting how the object is the same but people will look at it differently no matter what. Like our taste is different, our experiences, moods, every little occurrence has affected our likings in some way, and that's the same with aesthetics too. Even for the word "AESTHETIC" in the poster, some might read it as it is while some might read it as "ATTEHISEC".
