Great submissions, Modern Design. For #51, could you pursue this same idea using the red in the color swatch and perhaps strengthen the "S" emblem's resemblance to a ribbon? Also, it might be interesting to see the rectangle as a circle (maybe one with a gold variation).
#120 is interesting. We are leaning towards the medallion look. My concern with it, however, is how metallic the S looks. We are leaning towards incorporating the "flame" from the Shingo Institute logo that I attached. See if there is a way to make these medallions look and feel more consistent with that logo and you may have something very interesting.
