Hi!
I've just uploaded on my patreon the new tutorial about painting Celestine.
As you can see this tutorial is about painting armor on her back.
In general I prefer to paint much paler Gold NMM but on this model I wanted it to be much warmer and more yellow because of what the character represents.
Answering to your question: Yes, parts of these details will be hidden behind other details (like her backpack with wings) but they will be partially visible on some angles, and because of that I feel strong need to paint them.
I hope you like how the NMM looks like.
Regards
Flameon
