Pre-heresy thousand sons army

This is a project I started 8 months ago. After getting into the hobby though kill team, I want to build paint and play a full army.
I really enjoy the Thousand sons and their use of sorcery and warp powers so I went in that direction.
It's still quite in development: I found the colour scheme I want, which is a pre-heresy variant for the sons of Magnus, red and gold with bluish/purple tones for the fabrics blending into white. I have already refined this paint scheme multiple time and would like to push it further and further, improving the gold nmm and the overall readability of each model
