Expand the customization options, but still keep it limited as in don't just put every option possible but make sure each option is distinguishable from the next. I actually have a harder time deciding when there are too many options with very small differences with each other and would prefer smaller but recognizable options. Discrete sliders are preferred over continuous sliders.

That said, I also think the character customization is good enough as it is (minus the Viera/Hrothgar limitations, so fix that) and would rather they fix the clippings and the way gears work in various poses and their interactions with different appendages. But that's probably a more difficult thing to do.
