this is a great shot.
if you are looking for advice/ideas - with busy backgrounds you can try increasing the distance between model and background to make it a bit extra blurry - if the surroundings allow it, this is easier said than done.
I like shooting through branches or flowers to have them in the foreground (but thats a very different look then and may not always be what you want)
keep up the good work!
