Oblivions sliders allow far better control over the outcome, but I agree on hair, facial hair, even body hair (and length control for all).
But somehow I fell in love with the Eve system too, if I read it correctly and you can just drag stuff on the active setting. Very intuitive.
Oblivions shortcoming is the limited resolution, mesh and/or texture, and to a certain extent skin material. Oh, and lighting svcks.
I loved how in Eve you can create an awesome avatar picture of your character, by adjusting pose and lights. And sliders for bodily attributes.
So I would love to have at least one Photoshop/Paintshop in Skyrim, where you get to control where you look, pose, and lights, and have a snapshot exported in high quality Can think of a few cool quests related to this as well. We've been inside paintings and inside some weird movie. Time to take it to the previous level?
However, this only deals with the character looks creation, the avatar. No new ideas on how to do stats, skills, and custom class creation. As much as I loved the Fallout3 process (growing up), I doubt it would work very well in Skyrim. Maybe you are born. But the how you will look thing comes later, maybe in relation to a dream working as an omen of the future. Then you play with some kids and boink boink - guess where you wake up? Naturally with a lost memory In prison you will learn about the world and given the world map. Then you break out, and one of the quests will be to find back to your roots. Maybe the dream was from the breakout? Bah, carried away again...
I think I actually want some good old fashioned dice rolling as well as assigning remaining points. Also, luck should be a separate stat that you cannot advance in. You can influence your luck with spells and potions etc, but I think luck is something that should follow you.
