December 31, 2008 8:16am You have good control over the tonality here - the choice of white garment for model gives her prominence in the photo. The fact that you did not center her in the composition but left psychological room for her to walk into is very good - not many MM photographers do that. About the only suggestion I might give for improvement would be to use a smaller f/stop to limit depth of field to cause the background behind her to go slightly out of focus so that she stands out more. The latter can also be simulated in P/S to good effect during post processing.
