I'm afraid the picture is a bit tiny. If you want to build and fly it though, then DO IT!! You've got a picture you say is an amphibious, supersonic fighter, and you are asking if we want to see your build fly??!! Yes. Yes we do!
Amphibious. It goes under water, like a submarine. Supersonic. It breaks the sound barrier. Fighter? It's got guns!
It's faster than sound, can fly underwater and it has guns. It's pretty difficult to get cooler than that!
Two thumbs up from me. Just make it fly underwater and take off again and you've got my vote for the coolest build EVER!
