Looks kinda linear but good nonetheless! Some star locations are a bit too close from each-other tho so I'd might twerk that to try to unallow people to get 2 stars in one roll!
For the first junction, I'm not sure why people would take the longest one besides if there's a star in it but it's just minor complain.. I would switch the position of Bowser and Boo however since it's an easily accessible Boo, it would make more sense to pay from Bowser first to reduce star stealing but that's just my opinion. It looks like a fine board nonetheless! ^-^
