Don't pay any attention to the croppers, M (you might want to give us an actual name). There's not a single photograph posted on LuLa that the croppers aren't going to suggest cropping. As far as focus is concerned, if you check the work of Cartier-Bresson, who unquestionably was the most influential photographer of the twentieth century, you realize that sharp focus isn't critical in street photography.
The picture is fine just as it is. If you crop you're going to damage the graphical balance. Good shooting, and welcome to LuLa. Don't run off. I'd like to see more of your work.
