While your MKvsDC stage were not good at all, I must say this stage is pretty well done, the effects are nice, and even though there are a lot of them, they blend kinda well together and are not painful to the eyes at all.
The transition between the parts is okay, and there are no graphical bugs.
Only thing that bothers me is the position of the floor. It has this usual /|\ shape, and while placing the | in the center of the stage usually makes sense, I think it may have been better to place it in front of "the center of the background animations" (a bit more on the right).
Or what may have been even better would have been to center all the effects and BG elements perfectly instead of putting them a little on the right.
Apart from that, good job.
