what is subject in visual art?

answers1: Your question is unclear. <br>

Visual art is anything which we decide is art, and which we observe
with our eyes, as opposed to ears (music, poetry), noses (cooking,
perfume), etc. There is no restriction to what may be in the art. <br>

Some is representational - it depicts things in the real world. Some
is abstract, with no direct reference to objects. If you want to claim
that your textile wall hanging is inteded to evoke the smells of a
day-old battlefield, you can.
