The key element you have drawn our eye to in this image Mike is the old rusty BBQ grill. For me, this focal point cries out to be manipulated so that it glows yellow hot. If you select the grill and pan as an object and then play around with its luminance and hue, it almost looks like it is too hot to handle. Regarding those cinder block lines, I would just make the vertical edges to the right of the BBQ plate vertical and leave the horizontal lines diverging. There are also some interesting blues in the shadows that could be brought out a bit. The diagonals of the stools nicely offset the oval grill.
