Hi hi~!
She looks GORGEOUS. I love her eyes - so nice and sparkly!
It does look like you mirrored the eyes though - because the eye highlight is towards the middle on both of them so might want to be careful with that! I tend to leave the highlight out if I'm mirroring the eye and then I add it at the end to avoid that ^^
I think the pose could use a little work with how she's holding that scythe. Try doing that pose - I personally felt a lot of pull trying to get my arms back and towards the middle of my head like that while holding something. Also - her hands aren't actually gripping the staff of the scythe, more resting on them while the scythe relies on pressure against the neck to keep it in place.
When you do that sort of pose, holding something behind the neck, the item tends to rest against the neck for support. I've done the following to sketches based on some photos I took of myself (with a katana as I don't have a scythe or staff on hand to get a straight stick, but you get the point).
The image on the left is if you want to grip the staff with the hands, your chest opens up as your arm go out to the sides but your hands are pretty much parallel to where the staff is resting against the neck since that's all one straight line.
The image on the right is similar in what you were going for - a more relaxed, not actually gripping the staff but letting it rest on the base of the neck and across the shoulders.
I hope that makes sense ^^ it's really important as you start to improve your drawing to really THINK about the pose and how comfortable it actually is as opposed to how pretty it looks. Some poses look good but are actually super impractical. I've seen photoshoots where the models have given feedback to the photographers, saying a particular pose they wanted just wasn't physically comfortable/possible. If real people can't do it then neither can our characters ^^;
Oh - I'm not sure but it looks like you might be a bit uncertain about how to draw where the arms connect to the torso?
Hopefully this makes sense - I generally just go with this 'the breasts curve up then out to define the deltoid muscle - the gap beneath the deltoid then becomes the arm pit which goes back down to the torso, following the ribcage along the side but are covered by the breast as that comes forward' sorta thing.
Or real photo!
That aside, I do love her looks. You've got done a great job with her face and her hair!
