I think No. 3 works best, the portrait format works better than the landscape view. I would foto it more and with different light states. But, yeh stairs are cool, not weird. Look at Brassai shot of stairs in Paris, Kertesz' Mondrian's studio, etc.
Thanks I will check those out. This scene was surprisingly high contrast, the stairs themselves were very dark in tone (the material) in very heavy shade with the sun lit areas off the charts.
