You can seriously animate!
I just like watching that fighting part, scene 4. Especially when Shadow and Mario vs the Red and Black Koopa just get beat up really quickly. The first half was kind of story-like but the fighting, I just love it. I can't wait for part 5. Also there were two parts I saw some 3D effects, the part where tey're sping on the Koopas and the part where Mario hits Red through the hill. I seriously like how you made this!
