O_O I think I remember the Let it Rock video... That was one of both mine and my friend's favorites... That was made with WMM?! Are you serious? O.O I wouldn't have guessed that, it's too good. Seriously.... I've never been able to get anything that good on WMM... Is there something I'm missing here? Time, patience, that's not a problem, usually neither are ideas... even if I do focus, mine never come out very good...
Well if it's quality of the clips that you're struggling with, this guide on amv.org really helped me out a lothttp://www.animemusicvideos.org/guides/avtech31/index.html
It's the most up to date version of the guide, though I tend to use an older one myself, as I use an older version of the amv app than I probably should.
Also don't feel down about not making it into the contest. This will be my third attempt at the amv contest, and I've never made it in either, and I'm using Sony Vegas (Now adobe since I finally built my new computer and can run it), but in the years I've been attempting I really feel like my amv quality has improved. So I guess while I can see where you're coming from with the tiers thing, I still wouldn't like it even if it meant my amv got in to the contest, because it wouldn't help me improve any. Even looking at the amvs I've sent in to past cons, I still feel I've improved a lot. Just keep trying and I'm sure you and I will have our day when our amvs get in.
