Monster of the marshes

Out on a ride this afternoon, we spotted this interesting 'monster' sculpture on the edge of the marshes.
It is not far from the 'Man Bird' sculpture I blipped last year, and I believe it is the work of the same artist.
It already has a lovely rusty texture to it.
There is a photo of the whole monster in the extra. According to the information board nearby, its body is made from old gas cylinders.
