I don't mind the length. You could use some "rupture" or "shake" effects when the elements combine. Also I think the final spurt needs more emphasis. Like an explosion or charge up or something? but I love the 3d bit. 4/5.

i agree anipimp but i also agree that it should be longer, ur an awesome animator, but u need to focus on one animation at a time

4/5 . Good but i think you need to make it longer and should be fighting someone .
