Usually archers or "The Nightelf" in general are ready too kill, so the eyes here may need to be adjusted and also the mouth a little bit. Also, maybe a nice touch would be too add some leaves towards the green hood so it seems she's hiding too attack some enemies?
The tattoo's color is too intense. It seems like she is painted around the eyes.
Her hair and her hood could look a bit more natural.
The hood seems drawn randomly and this wouldn't help u to shade the hood, nor the face.
I suggest to refine her face and then, with the desired green hue and the color option of the brush, draw that tattoo.
If needed u can darken/burn it a bit.
Her eyes need shading as well.
The shading on her face must be smoother, to not look like dirty skin.
I suggest u to observe some hooded elf pics(artworks), they may help.
