Vince: Welcome to the sports corner and thanks for posting your images.
I like the idea of #1, but I'm not sure you've nailed the focus.
With #2, when in doubt, go high, meaning this would be a fine shot cropped at mid-thigh if you'd captured her hands, so if you have to choose between hands and feet, in this case, I'd go for the hands. Also, to my eye, WB on this one needs to be a bit warmer.
#3 definitely is the strongest, technically, of the bunch. Not a particularly interesting shot, though, which starts with the athlete.
#4 doesn't work for me. Either wait for her head/face to come down to where it is visible, or forget it. The full handstand on upper bar with full face is an easy grab, so this just doesn't cut it.
I like that #5 is different from the norm, but...
For posting, it would be helpful if you would reduce the size of your images to 800 pixels on the long side. Even with a decent sized monitor, I have to scroll to see all of one of these vertically oriented images.
Keep at it. I think #'s 1 and 2 show best your ability to see and capture interesting moments. Post more when you've got 'em.
