Great concept. I think you could have improved it by yourself moving a bit to the left so the old lady's head is not exactly in front of the corner, and have her turn slightly towards the frame. As it is, I'm lead to the right, and there are just a few cut off roses that don't really add to the composition.
I don't know but, I think I might have cropped that painting out behind her a bit more to focus on her as she is beautiful in and of herself but, I get that it's the concept you were going for.
