Douglas all the lines leading there were the reason I took the shot. All the lines lead to the woman in the window. The implied line form the lady in the lefts gaze and the lady on the right pointing has this great leading line all the way from her hand in the bottom right up her arm to where I want the eye to go. I saw the lady in the window and I was pre focused using the DoF scales on the lens and then the lady on the right raised her hand pointing at the lady in the window just as I started to walk by and I just hoped as I pushed the shutter the lady in the window didn't blink or look away. Gotta love those moments.
