I like this picture and think it stands out on its own. I'm not sure the title isn't working at cross-purposes with it, though. The aquamarine machine isopartially hidden by the stair rail and is kind of hard to see. The blue case in the upper left, on the other hand, draws the eye almost immediately. I don't know if there's any better title, though.
(I'll have to also admit that sewing machines was not my first thought when I saw "black singers" in the title.)
