Comments and critiques, please

These shots were taken during a dance performance, where no flash is allowed. So they are shot at a high ISO and therefore grainy. But in some of them, at least, I don't think the grain detracts too much.
Some have some photoshop work done to remove distractions in the background or to try and emphasize movement.
Tell me what you think and if you have some suggestions how on to do low-light actions shots, please let me know.

Long shutter speeds at dance performances (through the use of a tripod) are sometimes cool. You also could have made better use of your camera if you were shooting in Manual. For example: On shot #2 you could have opened up your aperture and shortened your shutter speed to reduce motion blur. You could have also chosen to lower your ISO if you were satisfied with a small amount of motion blur if you opened your aperture as well.
