Sun & Moon Warrior
First up on the new K3 unit list are the Sun & Moon Warrior. They are opposites to each other, the Sun warrior emphasizes offensive capablities where as the Moon Warrior is more agile.I used more jagged shapes and radial designs for the Sun warrior, while the Moon warrior has spirals and curves with a few meandering patterns. Personally I liked the Moon warrior with that weird moon shape coming out back in the sketches, but the game designers I worked with went with the one you see with colors.
The images below shows some of the references I used while coming up with the characters. My art director usually give me a set of images that I then process along with the written texts. I also crossreference the characters with an excel master file containing the character stats so I get an idea of what they are able to do.
