Not so good...
First, it is not "maked" it is "made".
Second, why would the flag fall like this??? Because Mario floated at it?? Glitch? It is not explicit enough...
Third, you got a good point when you made a battle mode appear in your animation, but you should work on it because there should be more moves for the time it takes to battle that monster. I tried to die... then I got a life out of nowhere to restart the battle... why would a life shroom appear in a such place underground?
Fourth, the animation is really short :( I wanted to see more... but that's only your's to decide this :P
To conclude, you can do better, just work on it. You deserve a 3/10
