Amazing!
Agree with Claredeth; but mostly, you must get rid of outlines: they seriously hamper the anim readability (mostly in the adam's apple). Shading and edge highlights which you already have in some places, will make a much better job with volumes.
@ orenshtiv: you're right... I've adjusted it already, but I've uploaded the wrong file XD
thanks for the nice comment, but I don't think this thing is going too far :D
That's GLEAMING the Cube. Nice work anyway :D
The foreshortening is bit inconsistent, but yeah it's a pain on something like this.
@Miss-BUG - so upload the real one,it would be much,much better! :)
