Dutch Imperial Sapeur - Bust

At the same time have been working in this one also in acrilycs.
Only the reds and gold on the left side are worked (and the face).
I would like to ask if the hair on the back shouldn’t be white (a wig) since he’s in full dress.
Once more I’m eager to hear your comments.

Cheers,
Paulo

The whites looks kinda flat for me, maybe cause the pictures, I guess you need to add more shadows. The rest of the work is pretty cool...
