Let's start with the official brief:

ART DESCRIPTION:

Setting: Innistrad

Color: Green spell

Location: In the farmlands of Gavony (see 37B, 38)

Action: Show a view from the top of a barn, looking down at some FIELDS OF CROPS where CULTIST PATTERNS have been BURNED—sort of like "crop circles," but using the shapes of the cultist symbols on 95. The result is a pattern of blackened, burned lines in otherwise healthy, green crops.

Focus: The patterns in the fields.

Mood: Weird stuff is happening here...

Ooooh! I remember when reading this for the first time I got really excited, this was a great opportunity to try out my new, and horrible, 3D skills. At this stage I was also asking for some other stuff than just lands so getting this was great. Dark mood, cool angle AND fire? Color me 30 hours lighter because Imma spend some time on this!

First things first, the 3D sketch.
