Could we also have a second variation of #163 the first being with no black background and the second being with a line and arrow following the top outline of the triangle so going up the side, back down the other side the peaking from the bottom corner up? if that makes sense?
#176 is the revision. i tried your idea of adding an arrow on top, i guess it just doesn't fit with this graphic. hope u like the revision with color changed to a more darker one...
