Great job with your piece, mate! There's a thing that's bothering me (and quite a lot to be honest) - the arm that is pointing the sword towards the other character. I get that it's supposed to be foreshortened, but we're looking almost straight at her profile, so it just looks like she has one normal arm and a very short one.
Also, she has a veeeeery strong expression (which I like) but the horse doesn't seem too bothered. Maybe make his nostrils a bit more "open" or whatever? Like this
And the foreground char's lifted hand kinda looks like she has three fingers missing. It is just the pose, but you might wanna revisit that to avoid confusion.
Okay, I'm looking over the painting again and I'll have to hang you for those blades of grass in the foreground (is it even grass?). They're just single, thin, textureless brush strokes! How am I supposed to admire your beautiful painting style when that's there?? xD

Oh, goddamn it! Yeah, you mentioned -two weeks ago- that you removed the "blocky" thingy from the top of her chest plate because it would hinder her movement. That is s'possed to be like a neck guard as far as I know, but it was used only in jousting tournaments, since people really liked smashing each other's lances in the face of the opponent and sometimes missed. It's not supposed to be practical and it is not supposed to allow head movement. Okay, now I'm gone.
