Buck Rogers Die Cast Toy - Maya + Substance Painter

I love old die cast toys - full of memories and history and they look so cool too!. They can be scratched and dented yet still don't fall apart. I I have a collection of these toys that i am planning on recreating in Maya and texturing in Substance Painter with custom materials.
I toned down some of the damage in most shots so it looked less toy like.
Renders are straight from Substance Painter iRender viewport.
