I thought it was pretty good, the style was nothing new, seen it before with all the other psycho-acid trip music video. But I will give you a plus for making it into a Christmas theme, so good job on that. Time for judgment.
Music: 8 Good trance mix, did you create it yourself of is it a track you got from someone else? Either way its good.
Animation: 7 Seems like you have some experience with this so, I would have to say its good.
Length: 5 Could of made it longer, but like you said in your movie your tablet stopped working.
Overall: 6.6 = 7
