Thank you so much!! I'm so sorry for getting to this so late! After Retrospring sent that message that they are closing down I completely forgot it existed.

I do have ref sheets for them, if you mean that. Their armor I designed myself. Especially Douglas' is very fantasy adjacent. Willows is inspired by a set of real life armor though, a riding armor from the local royal armory.

For general armor ref, I recently shared a drive with pics I took myself over on Bluesky. Here's the link to that post:

There is another persons armor drive in there as well. Else I can rec looking at museums. A big part of the austrians royal armory can be looked at on the site of the historical art museum. There's probably an english site but here's the link with the filter I use to scroll through the site.

Hope this helps, let me know if you need anything else.
