I associate Sunflowers more with Van Gogh myself Terri.
This is OK, it could be better.
The shadow is, to be honest, ugly and the texture of the wall doesn't fit the smoothness of the rest of the image.
I also find the dead leaf at the bottom left of the vase a little out of place and the blurred look it has competes with the book pages.
I personally would just like to see the vase of Sunflowers on their own without the other distractions, you are so good at those simple shots that have real impact (the peppers image for example).
