Hey ive been seeing lots of particle flames around and am wondering how the hell you figure out how much they are worth?

It really all depends on the color, style, and work put into it. (well reknowned people tend to have an slight price adjustment to their advantage)

However, my knowledge about particle flames is limited being as I was never truly interested in them(yet for some reason I know the correct y value to make them visible).

So let us wait for someone more knowledgable about the subject respond.
