I wouldn't say I was completely disappointed with the char gen, but there were certain things were we could have had better options, namely I feel the lack of mallebility with the noses is somewhat disappointing and the eyes as well.
being able to determine the nostril width and the sellion height and so forth would've gone a long way. especially with the dark elves, not alot of their noses I actually like.

so I guess my question is, with the Creation Kit coming out, how much do you think we'll be able to tweak the Char gen? maybe just adding new noses and such to it.

The character creation is a joke. The actual control of what the face looks like is minimal, most of the options are presets.

Yes, I expect adding nose shapes, eye shapes, etc. will be more than possible. But I imagine it will require actually modeling the new options.

Probably with the same level of control as we've had in Oblivion(the superior chargen).
