Well, let's use our minds and think for a moment.
Fan Art. Ok, let's figure this out.
Firt we can list some definitions.
Fan: 1. Those things that spin and keep us cooled down. 2. Someone who likes or follow something.
Art: Something made by someone with talent.
Ok, well. I don't think my fan can make art, so we can cross that one out. Now we have:
Someone who likes somethig and made something with talent. We are talking about GTA so let's throw that in there, too.
A GTA "fan"((using the word not the 'definition')) who made art.
Someone who makes art is an Artist, so that would be a Fan Artist, so we are still missing something. We want that to say Art, not Artist.
Something made by a GTA Fan using talent.
That would be Fan Art. But not fully what it is. Because I'm a fan and I made Skyline's sig, but that isn't fan art.
A peice of art made by a fan, about whatever it is they are a fan of. In this case, GTA. So the fan art would be fake screen shots, drawings of the characters, fake box arts, etc. Any type of art pertaining to the game.
Ok, I was bored and decided to draw this out long.
NOTE: The "definitions" I used were NOT real definitions, but rambled words used by me to describe a word. Thank you.
