Mark,
It looks like a good start - as Gidon says, they can be a never ending project though!
How will you achieve fine adustment of the fence? (it looks rather short by the way - there is no reason it cannot be as long as the table.
Typically, on a simple fence it helps to fix one end then move the other - so that you only get half the total movement at the bit position. When I used this kind of fence on my old tables, I used a small yachting turnbuckle to help get the fine adjustments I was seeking, it worked like a charm.
