It has possibility
There's not enough in the trailer to really make a good judgement about how it will be. From the trailer, I would say that you might need to be careful about voices - the evil laugh wasn't exceptional.
Reviews for "The Element Zone-Trailer"
Looks promising
Decent graphics and cool look characters. I hope you do make this into a full movie or movies. The ice axe was particularly cool looking.
It looks nice.
I think you should at least Try and make this, you have nice style, and the animation is smooth. I can't judge your plot yet so I suppose this trailer was nice.
