It seems most likely to me that the middle void in the Triforce symbol would be the representation of the Twilight Triforce. I mean, think about it; the way the two worlds are balanced is how each world defines the other, and the center void is what defines the Triforce itself.
That happens to me in ALL of my pics. But I know if I stop immediately, I will never get anything uploaded, so I just finish it up anyway. And I'm sure you have skills in the art department. If you need any help (if you have photoshop) I'm uploading nothing but tutorials for ps 6.0 and other versions for the next couple of days. If you just need tips and pointers for drawing byb hand or with a tablet or something, just ask me and I would be glad to help ^_^_^
hmm well that would have been an interesting thing for tp. another triforce for the twilight realm. hmm not a bad idea for a new loz game. If the twilight realm had a triforce link would have the twilight triforce of courage making him the link between both worlds or realm.
very good picture by the way
