Things of note: It doesn't really scream "archer" to me, and the pose is so stiff as to be unnatural.
That second version is actually a step down in my opinion too, with the additional color the sprite has lost a lot of the clarity the flats afforded it! I'd go back to the previous version and try to work in some minor tweaks instead like some minor shine on the hair, try to focus on keeping that clarity intact!

I also recommend doing some research on what archers usually wear, for example many of them have special wrist-protector gloves on their bow-holding arm to prevent their wrists getting skinned by the bowstring. Other things to consider: where does she keep her arrows? There are various kinds of quivers: the classic back-mounted one, the one mounted at the hip, I've even seen a few people with quivers that strap on to the thighs!
Finally, what kind of archer is she? Crossbow, longbow, shortbow..? each one requires different bolts or arrow sizes, as well as different gear.
Keep cracking at it, try for a more cell-shaded look too!

When in doubt, I use google and find hex codes to plonk in. I'm colorblind though, so I can't say I recommend that unless you want to start over-relying on a crutch you don't necessarily need!

I advise against the checker floor, it's a bit too easy to lose the characters in it.

Jaw doesn't connect on the left, makes it look off-center!
