Very nice shapes. I can appreciate it better because of the photo. The only very small change I would make is where the trees meet the sky on the upper left and form a small point that points out of the picture. The contrast of the dark sky against the white area draws my attention instead of the focal point, the railing and steps. It was a great idea to make the railing red.
We stair walk nearby daily at home. Up and down our three flights thirty times, plus whatever we do for daily life.
