I love the armor and the pattern of the tunic/fabric underneath. I also adore the fact that the female knight looks like a lady ready to go into battle. Not a lady wandering around in her underwear. Brava.
The discs on the shoulders of platemail always fascinated me. Their a bit unattractive and so we never see them on fantasy armor. but we should, because they served an important purpose: Keeping you from getting stabbed in the armpit.
I really like your style, you are very talented. The only thing disturbing me is that the characters look a bit cliché. A pretty girl with the standard, not a single scratch, girl face. And then the slightly older man with short brown hair, beard and some scars in the face. On the other hand, I'm super happy you've made some serious clothing and armor for the girl! It looks great.
