good times

I remember watching this under judgement and loving itcan't wait for the series.

Okay, I see a lot.

A lot of things that could and/or need to be improved upon.

As you mentioned this is simply a trailer, so I won't complain about length.
Animation SERIOUSLY needs improvement, as well as touch ups in the art presentation. Quite frankly, this could be classed as nothing more than sticks right now.
The sound quality was just plain horrible. I could barely make out the lyrics.
If those backgrounds you used or some of the frames aren't yours (because they didn't look like it to me) draw up your own. seriously, it'll go a long way towards making this better.

not bad at all

i hope you do something about the music...the backround is a bit iffy...the characters are a bit generic but im a fan of anime most charaters look alike... i like it

That audio...

You've got mostly some motion tweens, which is fine when you're just starting out, but that sound.... Man, that sound. You REALLY need to upgrade the quality of it, because it sounds like you just used your mic to record the radio or something.

It's be better if you fixed the audio.

But it's not bad otherwise.
