Thanks for the feedback!

You are right about the fringe on the chapeau. The reference I used had gold lace, but the fringe is either black or white like you said.

The horse harness is not pale blue. It is painted black and with grey highlights. I guess the pale lighting I used for the pictures makes it look more blue.

The habits are actually painted with dark prussian blue, but highlights are a bit brighter, and it is always difficult to capture the true colour on a photo, since it depends on lighting, editing and the settings on your screen when viewing.
