Brian,
Your stuff is truly great! Some stuff i have not been able to view because I'm on a mac, but what I have seen has been tremendous

In your case I guess it depends what you want to do. With the stuff you have, it's obvious you're not going for a character animation position like me...

What position are you looking for? Modeling? compositing? texturing? Jack of all trades?

Say you were going for modeling... I'd put all your stuff like you say you have it with the compositing.. then at the end, show some turn tables of your models in wireframe or untextured. Something like that...

Again, just remember to put only best stuff.. Best Stuff only! If it's a minute long, then it's a minute long. Only add to it if you feel you have something really great to show, that you think will add to your chances.

I read somewhere that you'll be judged by your worst piece in your demo reel, don't give'em a chance to find a worst piece, or make sure your worst piece is pretty darn good

Hope this helps buddy,
George
