Hey, your primary concern should be with her pose, it doesn't really make any sense and looks like different pieces of different figures have just been cut and pasted together, this isn't helped by the fact that you put her in some armor thing that covers any indication of her body twisting. Next, (although thinking about it this should probably be what you address before anything) you need to sort out what is actually going on. The image makes no sense. She standing on a cliff top or something with really dramatic views, yet for some obscure reason she seems more interested with something on the floor behind her. But she has her eyes closed?

The face and forehead seem to have different perspectives, and her bottom lip/chin looks like it's doing it's own thing as well viewpoint wise. If you are using reference then study it harder to get a feeling of where the features lie and how they turn in space depending on the angle of the head.

Background is looking a little airbrushy as well, clouds are light and fluffy but they have form.

Also I'd suggest doing some studies of metallic surfaces as your metal isn't reading well. There should be much more contrast.

It's pretty static as well, maybe have her hair blowing in the wind or something

Sorry to be so blunt, I've been getting a bit annoyed with people pussy-footing around critiques lately. Anyway, hopefully you find it helpful.

Keep painting!

Peace
