Star Citizen Workflow Study 2

I once again decided (since I like them much) to recreate a few props from Star Citizen concept art.
In this case I recreated the amazing props by Chris Doretz, which can be found here https://www.artstation.com/artwork/lxZv25
I absolutely love the style.
Here are a few renders with comparison with and without the 2 trimsheets driving these props.
There is a main master material with a few instances for color variations that drives all of the different materials on the props based on Vertex color (RGBA).
