some things I noticed: the ipod link is broken.
What codec did you use to encode the videos? On the computer at work I couldn't play them with the vanilla install of Quicktime. Just make sure it is a common codec, it might be something to do with the restricted system i'm on.
I'll add a few crits for the work on there and the demo reel (sorry if there was a different thread on this)
Rex is cool, i really like the design. Animation needs more weight as he steps, he is a big guy on little feet. Right leg also pops.
On the demo reel, one of the first shots was of the environment. It is a really dark shot . Either re-render brighter and move it further down the reel or remove it I'd say. Because it doesn't do you any good if you make someone stare at a blank screen for a few seconds.
Also the background color for the character turn-arounds. The first character blends in with the black. Maybe add a neutral gray on the background so people can see the texture. It will make it pop out a lot more.
off topic: was that you showing Rosa Tyson's website the other day? I don't think we've met
