I like what your going for - emotive. I also like the way the window is framed by the plant. However, as it stands this image is a bit flat. In future, make sure it's closer to 640 pixels on its longest side.
Also, you should try playing around with curves/contrast to give it a little punch. If you're stuck without proper image editing software (as I am), download the GIMP. It's a great program and free.
