I edit this using Photoshop
Vector art is created using vector illustration software programs, such as Adobe Illustrator or Corel Draw. These programs use mathematic equations and geometric primitives (points, lines, and shapes) to create art that is clean, camera ready, and can be scaled infinitely, without any loss of quality or fidelity.
As I was surfing on the internet, I saw my friend on twitter had this kind of art, they called it vector art. I saw my sister editing something on Photoshop like what I saw on twitter, so I ask for her help and she taught me.
