I am not sure as to why i feel this way, but i think the images you took of danielle in the same? spot is better. There is a better feel to the images of danielle, even though these are technically better shots. I think it has to do with the dress used being "too fine" for the graffiti scene.
Even if i'm saying this, the images are very good, but they lack a bit of the feel you usually have.
Just my 2cents, and don't take it as anything more, since you obviously are alot better at photography than i will ever be!
PS: The fifth image is very good, and has the perfect feel according to my standards! The dress fit very well with the dark background and the small lighted area around the girl surrounded by the graffiti
