The better of the last two is the lst one since it has no motion blur, but the composition is unbalenced and lacks a main focal subject.
Of all the others I like #1 with the light shining through the dress. The motion blur isn't so obvious in this one like it is in the others.
Were you using a telephoto lens? If you get to re-shoot at some time try using a fast (f2.8) wider lens (28mm?) This will enable you to use a faster shutter speed and the wider lens will help to reduce the blur.
The camera is Lumix FZ 7. I can only go down as low as FZ 2.8. ISO I think it was 100. Now I come to believe my fault was more to do with the mismatching shutter speed. I didn't adjust promptly and just kept Simple Mode setting.
I'm still not acquainted well enough with my Lumix camera, so I need to practise more.
PlasticSpanner, I recut the second last photo, hope now it looks more balanced.
