A while back I discovered a great tool for animators to get feedback on shots they are working on, it's called SyncSketch and it's great!

Anyone can draw on your video footage to point out problems in the shot add or add comments on individual frames, the video can be scrubbed through frame by frame. You can also change the frame rate of the clip if you think the timing might be off and see how things look faster and slower. If you are looking for feedback and want to improve your animation I really recommend you try it out.
