I usually really like your portraits, but I'm missing a bit how you wanted to portrait your model.
Your pretty model, has quite a stern look which for me doesn't match the 'cloudy' white background.
The wrinkles in the sheets and the plants also work a bit distracting.
A solid dark background maybe had worked better.
I'm no portrait photographer at all, so I couldn't have done it better, but just wanted to share my opinion.

I agree with you that the 1st shot is the best shot.
