I'll take a look. I do see an issue. You have the portal included in the Right Four Yellow bonus.
EDIT - One thing that might be an issue balance wise is the pink/aqua ones don't have any fast bonuses. The others have 1 for 3 bonuses. Not sure how that would play out.
Suggestion - you should put a colored border under the shared territories in the middle. So like Center Red, Blue, etc. You have 2 for each color shown. I would make the black 7 on top (so those are all shown black), then offset them as a path and color them. Like this (2 minute MS paint job, but you get the picture):http://i58.tinypic.com/2cpqavn.png
This way the middle are black territories, but it is shown they also belong to 2 or more other bonuses as well.
