I was checking if i have taken pictures while i was drawing but didn't find it.

Basically :

• i sketched with pencil, for the elephants i used random pictures from elephants as reference

• then i outlined the triangle and the lines of the 3 elephants

• i colored with watercolor and color pencil

• and finally with some wet paper and temper color i done something like clouds overall

• and some year later i scanned and reworked digitally with a wacom tablet and photoshop :)
