I think I would have liked this image better in it's original orientation better, the tunnel is certainly serpentine no need to confuse the viewer in my opinion. 5
The black and white really showcases all the details and great contrasts in this twisting path! It took me a moment but I love how you turned things upside down so now my eye follows the line of lights as it emerges from the bottom left corner to snake it's way to the 'horizon'.
