Contrasts. The woman on the looks homeless and hungry. The lady on the street has some pizza. I think you should not have cut the lady on the right off in the middle. She accually looks more of a distraction. This would have been a stronger picture with just the lady on the left. I put a piece of paper covering the person on the right and cropped her out. This accually made for a stronger picture. Your sole attention would have been on the homeless person. Try it out when you get the chance.
