Exploration mecha concept art

Exploration mecha concept art, I imagine this machine as a kind of big exoskeleton for exploring and also to work on construction of facilities in planets without atmosphere, moons and hazardous environments. The cockpit is sealed and armored to protect the pilot in hostile environments, the interior of the cockpit was inspired by the panels of a fighter aircraft.
I called it Naerval because the body /head resembles a kind of whale and it was supposed to have a long communication antennae similar to a Naerval´s horn, but it the end I removed it.
I made sketches of three versions before choosing the definitive form.
