Uh.... eh?
It was really good of you to remake the Megaman 2 ending, something I always thought needed more tacked on... but owww! The GUITAR! THE GUITAR! It made me want to throw a shoe out the window at something.
The robots were well done except that Mega Man's body segments blended together like the back of a centipede... they kind of needed some delineation.
The end tune and the animated stars seemed a lot more like genuine Mega Man. If you maybe went with that sound and look on your next project it might get some better reviews. I don't think you deserve a really low score, I just think a little more practice would be helpful.
