In street photography, there is a lack of consensus of where eye contact with the camera is important or if it is not.
There is also a lack of consensus of whether images should stick to monochrome or if colour is acceptable.
I tend to be quite pragmatic about both these points; it doesn't matter so long as the image is effective. Sometimes eye contact with the camera is critical while at other times it would not work. B&W was the default (and sometimes only) option in the early days of this genre. Nowadays colour is the default and we need a specific reason to shoot in B&W, for instance to simplify the scene.
Here is a street image that I've always found enchanting somehow. It was taken in the small town of Nandgaon, India. The young woman seemed to be interested in what I was doing and made perfect eye contact with my camera.
