A tad rough. Still.
I'm not certain how skilled you were before making this, but I would expect after four other animations in this style it would look a BIT smoother than the others. Not only that, but there was too much of the animation where it was off-center, and most of the action was occurring to the far right or left of the screen.
And I know you said that your computer was messed up, but I think that you could have waited a few more seconds for the Eliminator to come back up the cliff because that was just ridiculous in the timing.
Something to consider,
