This was an interesting board! The large amount of Red Spaces caused a variety of 1-vs-3 and 2-vs-2 minigames to show up. Also like how you managed to create a toll on junctions using the Koopa Banks. It's also really nice just to have working Happening Spaces!
The only complaint I would really have is the background, but of course not everyone is an amazing artist, haha. Also, the Koopa Kids are always in the way, but hey, it's Koopa Kid Land after all! It also felt a bit odd to have the tolls be on the outside, (seemingly) longer paths, though they do contain the Boo and Shop. But it felt odd that the shortcut to the next Star was free. Well, take that how you will. It was still a good board overall!
