Car Paint Material question

Hey there,

i am trying to recreate this “green mamba” color from Porsche on this Taycan Model.
im just starting off with rendering and especially with creating / modifying Textures and shaders.

It feels a bit flat to me, are there any Pro-tips or suggestions to make it even more realistic… I assume its the little little details that make the difference that I still don’t know of.

I uploaded the shader on Wetransfer: https://we.tl/t-OmULIk4hgX
Thx a lot in advanced!
