Dracula South of the Border...
I liked the story line, and although I speak very little Spanish, the music did seem to tell the story. The artwork was generally nice, but there were some places it was a little "loose" (like some of the people in the background when she's walking with the sword to kill the vampire, or when the vampire opened his mouth WAY too wide). Also, the walking motion could have been a little smoother - but that will come in practice.
You did a lot of work using tweens - I think if you replaced some of the tween action with FBF, and took a little time, this would really be a sweet video. It is definitely one of the better one's I've seen, and I really would like to see some more of your work - with maybe some minor improvements.
And, also, for us Gringos out here, maybe English subtitles to that song?
Keep up the great work - you have a lot of potential!
