I like the pose - the space between arms and body is perfect. It is just something I have started doing with bridal portraits if it can be done without looking fake - ie fixing the dress to lay smoothly against the body - it can be done very quickly with liquify and then if there is a fold in the dress such as this type of dress, the Clone stamp can work very well. It is either something you want to do and think it looks better or not - it is a style thing. I have found that if she really likes the picture, which this picture has great light, then if the dress looks perfect, she, mom or dad, or husband may want a big canvas print.
I did this in 45 seconds to give you an idea - I could make it look cleaner for sure with another 2 minutes.
Much improved. Takes the focus off of dress issues and back to her face where it belongs.
