Entry For Shadow Hunters Community SMASh Contest- Round 434 -pouring concrete into the foundation

Last year, I went to photograph the pouring of concrete into the foundation of a 6-story apartment building. My friend was a structural engineer, so he let me take the photos. I took a lot of photos and videos. In between taking the photos and pouring the concrete, I went to a higher place to photograph the foundation, because the sun was behind me, my shadow was clearly visible in the photo. When I took this photo, my shadow falling in the photo was interesting to me, and I didn't expect that one day I would use this photo for a challenge.

Here is a link of short video of the day :
