All: Fully custom torsos. HF torso's mere existence in these sets makes the torsos failures, except at certain angles.
Tahu: Change the lower legs, they break the color placement/styling for me.
Gali: Remove the gold and yellow, and possibly replace all the silver with gunmetal. More feminine torso.
Lewa: Replace keetorange with lime, replace gunmetal with silver if possible. Get rid of the chest plate, and give him better shoulder armor.
Pohatu: Fix the color distribution, and give him more biomechanical parts.
Onua: Possibly get rid of the silver. Might even get rid of the gold and make him look more like '01 Onua with purple.
Kopaka: Get rid of the chest plate and fix the legs.
