Oh dear lord.
1. Try making an ending to the video. Here's a concept: In a music video, the video ends with the music. If your video is too long, don't loop the music, SHORTEN THE VIDEO.
2. Believe it or not, people don't care if this is your first video or your tenth. If it's bad, it's bad, and people will tell you. And this is BAD. If it's your first, then make new ones and practice and wait until you have something presentable to submit.
3. READ THE SUBMISSION GUIDELINES. If something is a updated version, update the previous file, don't submit part two as a seperate file. Not only does it make you look stupid, but it pisses people off, and it's against the rules besides.
You get a zero from me. This isn't the place to test out your first flash video on people, it's a place to show off finished work that you're proud of.
