#1 is, I think, a good idea.
She is doing something that is at variance with the way she is dressed.
I can’t help thinking that she is a little static like she was holding the pose for you.
If she had have been actually sweeping, maybe movement in the brush.
I’m being a bit tough I suppose but nicely taken.
#2 catches the cheeky pose well. I am presuming that was the intention.
DOF works well.
#3 is my favourite. I would prefer if she was looking into the lens. In my opinion
this would have really improved. Nevertheless I think it is really good.
