Take care when exposing sunlit things when there is also a have shadows, this is tricky. Since the background is rather distracting I think you should have used wider apperture to blurr it out and concentrate the focus on the main subject. This can also be tricky in sunlit thing since then you have to use extreamly fast shutter speed and maybe ND-filter or some lightcapturing glass.
To be honest I dont find this image not good or eyecaching and also I find it technically bad.
I like big machinery for some reason. The generator adds scale to give the feeling of the power and strength of the arm. I like the shadowing for texture.
