I can see the Image fine, What size did you render it, and how many fps. Very Nice Dynamic effects. Was that in Poser 5 or Poser 6. The only flaw I see is her feet sceem to slide across the floor while spinning, and her upper body sceems just a little stiff. Getting a person to spin correctly is difficult if you use poses and have IK on. I had a simular spinning motion using poses, One pose I used from my pose files was looking one way and the other pose was looking the oposite from the pose files.
I tried every way I could, but when she was put into motion her feet mangled up and was a pain to correct (Note I spun the body and matched her foots location with a little foot prop I use so her feet don't move from it's location). I tried memory dots when I had the girl set up in position I wanted to no avail. I also spun the girl around to the correct position with out IK. but every thing I did didn't work. Even with the memory dots she came up in the wrong direction when I used the pose dot without IK on.
I can see your concentration is getting the hair and dress effect to push it to really move. Did that really bog you computer down? I here dynamic hair and clothing do that.
I'm waiting for Poser 6. I'm not completely happy with poser 5. I don't like their Charatures. But Poser 6 Charactures look really good, a good change of pace to Vicky3 and Mike3 which I like very much.
A real good job over all.
