Well, I'm no pixel art expert, but I'd have no issue playing a game with those sprites in it

I think they're quite good~
One thing I'd recommend is maybe moving the left arm just a tiny bit ahead, maybe so you can see another column of pixels on the hand. Right now at native res it seems a tad small. Or maybe instead of making it bigger you can lighten it up a bit. I know it's a hand based on my knowledge of human anatomy, but it doesn't QUITE read as one to me, it's a bit too small and/or dark.
There's also a very slight bit of weirdness with the tunic near the right hand, it looks to me like there should maybe be a few transparent pixels in places where there are colored ones. Specifically right beneath the thumb and to the right of the fingers, notice at native res it looks like they have a lump on the outside of their leg.
All in all lovely work!
