The character customization is pretty decent i think as it is. there's quite a lot of varety in what you can do...

my most wanted feature though would probably be less of a feature and more of a fox for all those damn clipping issues you get..

i think thats what makes character customization feel as limited as it can because hey there 50 hairstyles to choose from but only 5 that dont have serious clipping issues... makes your choices feel so much more limited.
