Hey I’m not a guru on post processing. Could you please note what type of post processing methods you used? The final images just looks so much better than the render.
Great job
Cheers
Thanks, man! 
But I’m not a guru either, hehe.
I basically used most methods I saw here in this video by Gleb Alexandrov
So, I applied some chromatic aberration and camera distortion, put a slightly blueish in the curves, added some particles with low oppacity wherever I saw light and glow the bright areas by painting and setting up the paint layer to Soft Light mode. Also, duplicate the original layer, increased the contrast values and set the layer to “multiply”. Anyway, I’m still a beginner and probably made a lot of mistakes here, but I think I’m in the right direction.
