in regards to the mastery images, i have a couple of questions!

1. does it have to be official art? or can fanart also be used?
2. and when you mean must "fit the theme", for hallows eve/blood red/jack o'lantern... what kind of image do you mean like just... matching the colors? so for blood red, there has to be red in the picture? or do you want it to fit the halloween theme so... there has to be blood in the picture?

HAHA these questions sound so dumb, so sorry for that, but i'm very excited!
