For the first time, and perhaps it´ll take lots of time to draw another transport XD
There´s the flying ship of Neptune, The Black Leviathan.
From the beginning, Neptune stole an old ship that was kept in an abandoned museum. He took it and he use it to go in most of the possibe labs to stole some machinary to customize his ship and make it more powerful. Cannons and propellers, thanks to that is now a flying ship with weapons.
NOTE: Remember that the story were Neptune appears takes place in the Earth where most of the planet is lacking of natured life. In this case, I wanted to kept the blue ocean because I want to show a beauty for the pic and it´s the first time I draw a ship, so it´s worthy XD
A big and warm special thanks to TiHavok for helping me with the basics characteristics of the design and for his advices.
