That'd be fine, Eastriel. xD I don't mind if you take a photo of what you draw. (Or even if you have to use a mouse in an online paint program. 8D)

And yes - writers will get a picture and artists will get either a picture to draw their own interpretation of or a written description.

For example...

I show someone a photograph of an apple pie.

The writer describes it as, "A round dessert with a lattice pattern made of its brown crust. Served hot."

The artist (let's pretend) doesn't interpret that as a 'pie' and draws a ball-shaped dessert with Xes on it and steam.

Then the next person down the line only sees the ball-shaped drawing and interprets that; etc.

Hopefully I'm making sense. xD It's nearly 5am. D:
