I found this awesome concept by https://www.artstation.com/andremealha
So i tired to reproduce it in Blender. I used hard surface modeling for the base mesh and added some details in zBrush. After modeling, I used Substance Painter to get the textures right.
Rendered in Blender Cycles. Maybe I give the new prerelease of Blender 2.8 a chance and do an animation with its new EEVEE render engine.
Pretty good but I find the original concept to have better colors (more vibrant and warm) and more detail on the cockpit. In fact it shows the separation of metallic parts better overall.
And I find the view angle better too (still on the original). More turned towards profile view, feels more satisfying for a fast moving object (plus in your case it would hide the deception of your flat water splashes).
Well he tricked me with those splashing water planes. It really doesnt look flat to me. I was going to ask how he did that, then noticed the screengrab with the planes in it.
I find this 3d concept very well done as he has made in 3d of just 1 2d concept sketch. Ever tried to model a 3d object by using a single image?
