I like the soft focus. I like the mood and classic dandelion. But dodging the hand and dandelion puzzles me over the light source. Hair light is great. A reflector or a properly adjusted fill flash would have nailed this portrait even harder. I just have to comment on the model, she is gorgious. Totally awesome hair.
Try a tighter crop and see what you think. crop from the elbow on the right side. with that elbow in the lower right corner, you would have a powerful lead in line to direct the view to the dandelion and face. And the face would fill a third quadrant.
You've got a lot to play with in this picture and you'll probably keep comming up with winner variations no matter how you slice it.
