I have only one problem with this awesome looking craft; the nose is angled downwards. If that hits the water at speed, say during landing, the whole thing might either tear itself apart, or (very breifly) try to become a submarine.
When I design something new, I always try to make it looks natural, like using proper lines. I think this is why it looks like whale. and sometimes I introduce something from real thing, such as Catalina's turret.
As I replied on your last post, I don't draw realistic weapon, also things I am drawing is based on my project, that is about a story on another planet. They have an ancient engine that can make fly, and their technology is based on it. This is why this plane doesn't have engine that we normally think. There are more and more planes that you think "something is missing" "it never fly" in my gallery.
Designing something exotic is my motto, people can recognize it is plane but something is different, this is what I want people feel when they see my picture.
