The important thing in design is to convey the message according to what I learned from design course. For example client has something want to say to receiver ex consumer. And designer encode the message to design to convey the message to receiver.
In Unity , particle system is like shooting rectangle shape polygon with texture image on it.
So if you want to express effect , you prepare the texture image and set it on particle to get the vfx effect you want.
