Here we go with the first exchange.
Starting today until the 31st of March you can add charactersheets and data of your OCs.

Necersarry Information:

In this case it is up to you. As most of you know it is far easier to draw a character if you have a reference picture.
If not you should add a really detailed describtion of your character same with other data (eyecoloer, piercings, details like scars etc). Same with background-wishes and Co.

So, for short, add all details that artists should keep in mind while drawing your character.

Have fun!
