Interesting concept, but I think the point (the strength of the crane lifting the large object) is lost by having such a wide angle view. On the other hand, the wide angle helps give it some scale.
Neat idea for the challenge. I think it would need to be lifting something that looks really heavy to have an impact. Clean, clear shot, just not much punch.
Laking in composition, too much empty space
The art of arranging elements of a scene or image in such a way that they are visually pleasing, emotionally moving, etc.
I wish I could see the crane lifting up something that looks very heavy or interesting. The triangle formed by the edge of the roof leading up to the top of the crane really makes the photo balanced. However the lack of anything really interesting in the photo to make a focus point keeps the photo in just the average range.
