That is really cool, thanks for sharing!
I can add for the English Civil War (1640s) the "shot" (men with muskets) are not generally wearing armour. The pike are supposed to, but a lot of units either don't have armour at all or have buff coats instead of a cuirass.
Cavalry is also often either partially armoured or not armoured at all, but varies by unit.
After that, armour for cavalry drops off very quickly and disappears almost entirely for infantry.
