Looks like a lot of fun! I'd give it a 7.5/10, regarding the flow or logic of the stage, some areas kinda give access to other areas but it seems as though splines pull you away. I would find it better if there was a reason to go in each direction, like x way is blocked. Also, around 1:10 the boards look kinda weird, like issues with the normals. The music could also use some work, and play throughout the whole stage. Overall, though, the stage looks great!
