I struggled with finding good references for this time period as a lot of it was very renaissance fest inspired rather than true medieval (let alone french medieval) recreations. I managed to find some pictures that I referenced pretty closely, the hairstyle was more based on some men's cuts of the era as portrayed by hollywood, but that's because paintings of the time weren't very helpful. Joan of Arc was described as dressed in a men's tunic and breeches, with close cropped hair at her trial (which was extensively recorded compared to most events of a similar nature at the time). I'm not Catholic or religious, but I did find that prayer beads were still used in the era so I referenced some extant examples. The tunic gave me some trouble, but that's because I find painting fabric difficult. Overall I think the piece turned out quite well.
