I don't know if you need the last 3 about appearance. Plus "brown" for skin colour is a bit vague It could mean anything from just tanned Caucasian to African.
No, it will, I'm sure. It did with the ones Josh added to his chars' pages. If you structure pages the way we do, and add the same little images for the abilities, it'll mess it up.
With mental creation, would the stuff created only be invisible to others, or also intangible, inaudible etc? And would that mean they couldn't be used on others/have an effect on others?
