I like the pose
But, I have a suggestion.
In DAZ, if you double click Vicky, you select her whole body. You should get a window down the side with general morphs and stuff. There will be one saying pregnant. If you fiddle with the one it changes her whole body to pregnancy, the effects on the hips etc too. If you are using the morphing dress, right click on it and Fit To Vicky and it will shape to her form now matter how big the bump.
It will look alot more natural, it looks there like you have morped the lower half of the dress but not the top half.
Took me a while to figure it out at first hehe.
