This photo, I think, would be so much lovelier if the background and other ladies were not blurred out. I like the choice of sepia tint, and I the shady/sunny spots really give this a nice, warm, fuzzy feel.
Not very effective blurr effect for my opinon. This should have been done much more carefully or simply use some other setup. Actually I think this could have been nice image without the blurr.
Photoshop to make more out of a quick snapshot usually doesn't work. I know that you probably didn't plan this shot, and pose them, or you would have removed the walker, the purses and had them more posed. The sepia treament as well as the blur do little to add to the shot.
The blurring of everything else in shot, including some of the subject's own hair, looks very unnatural and makes the subject look like she was pasted into the photo in some places. I think a more natural treatment would have suited this lovely photo much better.
The DOF in this looks a bit processed. I'm not sure if this is intentional or not, but I think the blurry woman (especially the one in front) takes away from the strength oft the image. The woman in behind looks believably blurred, but the woman in the front does not. 6
