Long time ago one of my favorite games was (and still is) Heroes of Might & Magic III. Time has passed since playing that game but what I liked about it was the creature upgrade property. At the beginning the creature was this basic/regular design of some race for example orc. By buying upgraded version of this “factory or building” that produced these creatures, you were able to acquire an upgraded version of this very same creature. What was cool about it was that the creature was the same but with an added coolness to it, costume color, skin color or overall design. So the basis for this drawing was to create a regular version of chicken ( or rooster or a combination of those) and upgrade it to a champion version.
