DuTwan, you bring up some good points, don't worry about coming across as negative.
Personally, why I don't like Dooku saying Obi-Wan should join him and help him destroy the Sith, is because it is a pretty big statement, that is never followed up on. Why does he say that? Does he really want to destroy the Sith? Or simply want Obi-Wan to join his cause? It seems like such a random line.
The prequels, and especially AOTC do this a lot: what the prophecy is actually about isn't mentioned untill ROTS and the mystery of who ordered the clones is never solved. Also, Dooku states that the Trade Federation was betrayed by Sidious, and came to him for help, but in ROTS, they are seen talking to Sidious. In my opinion, all these little things are just illogical, contradictory, and confusing.
Bingowings, that picture of Dooku on the Jedi council looks really good! Great job man. I couldn't think of a way to do it, but this looks like something we could actually pull off. We need to give him other hands though, I think Plo Koon would like his back :P
