Spaceship - 3D scene - Compositing

So here's the breakdown of my latest CG Space scene
.
I did the scene setup/Layout in Maya and lighting & Rendering using Arnold renderer, i also rendered DEEP AOVs. it took me 260+ hours to render (probably more than that :P)

Workflow is obviously Aces CG and Resolution is 2K !

Made the BG DMP in nuke using multiple stocks,

In the Comping i did the LookDev, making it look more textured, dirty & crunchy specy details. also did Relighting on Huge Spaceship to create reflective light of BG Planet.
.
The the small asteroids circle around BG planet was created using Nuke Particles system, also the Spaceship Thursters FX and the sprites of it, THIS WAS THE BEST PART! i loved to create this FX in Nuke.
.
the process was very simple though. And about the flares, i'm fan of Lens effects & Flares, so i added multiple lens flares on same frames & also on different frames, on top of that added texture on Lens flare, as it makes it look more natural & awesome. there was lot more stuff i did in this shot like projection mapping the textures, 3D to 2D in nuke and MANY more !
.
Speceships Models & Textures i downloaded from CGTraders.

Thank you so Much !! Have a Great Day !
