Anti-gravity military vessel

My very first scifi ship, that I created for my game project "Project Pangea". The ship is navigating by creating its own micro curvatures in local spacetime, thus being able to counteract the planet's gravity pull. By shifting the strenth of the anti-gravity field between the three AG-spheres it can freely move around without the need for an ignition engine.
The whole model was sculpted, auto-retopoed and unwrapped in 3D Coat. Texturing was done in Substance Painter. Final shader setup and rendering in Blender Eevee.
