Really like her expression in the first image and the way the light is interacting with her legs, the bench, and her face. Seems like there could/should be a secondary light adding definition or separation to her torso though.
I agree that the plant tower in the second image could have been positioned out from behind her body (someone should have moved it for you, how heavy can it actually be?)
Again the light is doing amazing things on her legs, the bench, and the ground immediately surrounding her feet in the third image.
Perhaps all three images could use a bit of contrast applied via curves. I really dig the foregrounds and subject in 1 & 3, the backgrounds are the weaker elements in these images. Nice job though.
