Thanks! I settled on the third one (Geometric elemental patterns). As for Selena, I am thinking of going for a more wave like pattern as a rework. I did circles as a test run because each of the team members are a associated with a different shape (Flare=Triangle, Takeru=Diamond, Bryce=Hexagon, Huky=Square, Zephyr=Wavy Line, Selena=Circle).
Also, Option 2.5 was inspired by the DX Ninja suits from Ninjago with the whole "dragon breathing out its wearer's element" design.
