I have just begun catching up with uploading all of my various little slivers of animation all over the internet, and I have found that above all others, the best way to get useful, immediate, usable feedback on your work has to be Sweatbox. It is a section of YouAnimator.com devoted to work in progress pieces. I uploaded a play blast I was working on and within 5 minutes got a very long, detailed comment of ways to approach the shot and add flare to it. If you guys don't have anyone to critique your work, I would most definitely say throw it up on Sweatbox and see what happens - and don't worry it's all very friendly!
