It was smooth as the the ball "revs" up [Dunno how to say it =S] so that was good. You did say it was simple/bland. I think its true and that could be the downfall for this animation.
Maybe you could add details in it like when the ball thingy spins you could add maybe some electricity and as the beam blasts straight you could maybe add different shade of colors to the core of the beam.
For example- My beam in the joint. -I've added electricity, tranparency circles and other strip of colors.
Anywaysz it was a good beam :D and you have plenty of room for improvement.
