We have no plans currently do add any form of customization to the character model and this is unlikely to change. As other have pointed out, the game uses pre-rendered graphics and the way we handle sprites requires every armor-weapon combination to be rendered for every animation. Adding another variable there (such as skin or hair color) would increase the number of combinations substantially.So other than adding new visual armor types, we're unlikely to add new variables unless they'll provide some gameplay benefit in addition to the aesthetics.
