If you enter the character creator and are unable to zoom in on your character's face to customize it properly, finish that character as a "junk" character (don't use the name you want to have for your real character) and enter the world, then log out to the character creator and create a new character. This one you should be able to zoom in on and customize properly.
This is a known issue and will be fixed, but for now this workaround can be used.
