You caught a very nice pose here in great light and got good detail in the lights and darks. The exposure looks perfect! I think this would play well as a horizontal or squarish format, if the sides are where you have more canvas. It would be regarded by some as a bit tight in the frame. It would also be good to level the "horizon" if the original capture has the room. (if not, many people will add canvas and fill n the missing areas with cloning or content aware fill.)
