Nice rose Justin.
Just one suggestion -- along the top edge of the flower, it looks like the mask did not extend all the way to the edge of the petals. Converting the background to black and white makes that all the more obvious. I'm not a PS user, so my terminology may not be exactly right, but try to feather and/or blur the mask slightly to get it to cover the edges. [You might also consider decreasing the brightness of the background so that it does not compete as strongly with the rose.]
