3D War Machine - Blender 3D

This one is built on a refrence I found on Pinterest and cant name the really concept sketch artist of the same, cos I couldnt find it. Of all the things done, Unwrapping has been a really tough task for me and second thing is the edge detection for Damaged edges , but in the end I am satisfied with what I have. Pls comment and advice ....

Used Blender 3D Only nothing Else
Renderd in : EEVEE (Eevee is my favourite these days fast and attractive outputs)
