I agree that getting feedback is very useful - getting critical feedback can be a little harder. I find the best way is for conference organisers to offer a post-session method of feedback on their website. Sometimes people can come away from a session quite happy, but after sleeping on it realise that maybe there were some improvements to be made. If you're worried about your speaking then recording yourself and watching the playback can also really help. You might realise that what you thought was a normal talking speed was actually really, really fast. When I was a TA my university made it mandatory for us all to peer review tapes of us all giving a short talk.
