2 red bourelets over helms. Both have gold details. This seems to be the most common way to wear a bourelet in this decade.

Peacock plume rises from the centre top of a helm, without visible attachment.

Crossed over string of beads on the far right helm?

Angry horses. Huge flower pauldrons. A massive crown. a single ostrich feather attached by a gold brooch to the centre front of a helm, or maybe a silver bourelet on a helm. The artist uses different brush strikes on the item that could be a silver bourelet to the red bourelet that is worn by the rider on the left, though.

Blob crest? Short, curly feathers? Short, extra dagged mantle?

2 thin feathers attached to the right side beneath the ear roundel. Note the man with the sleeveless arming jack. It could also be argued that this jack simply has different coloured sleeves, and is made in the grand aissette style.

2 slender feathers attached to the centre front join in the crown and the brim/fixed visor on the helm. There is what could be a gold torse, though it is more likely to be part of the helm. And another man in a sleeveless jack.

You rarely see hair from under a helm, so I will guess this is the artists rendition of a thick bourelet with a slim torse and free tails on top.
multi-tail mantling under a crown. There is a black tall cylindrical plume rising from the crown, between 2 horns that seem to be tipped in blood. There also seems to be a small flag on top of each horn. Extravagant.
I believe this was on the cover of a book. There is a small torse, and some other crest items, though they are hard to see.
