This is very well done! Kudos. The braid is leading the eye towards her face and nicely framing her figure, and really well executed. The face has a quizzical look. The fur is well-rendered. The glowing golden threads are adding a little color and interest. I think my only objection would be the background blue glow. I'm under the impression you're trying to indicate a glowing horizon on a cold dark night. However it kind of looks like the mountain is glowing. This hurts the composition a little bit, because it's a little bit too bright and therefore competes with the foreground theme, which you are trying to emphasize. Also, the bell-shaped mountain looks as if it's a frame/halo of the girl's figure, because it's following her contour. If the horizon were a little more straight and sloping towards the left, I think it would be quite a bit more powerful.
Hi Crucifixus. This is my critique. It is a depiction of a crucified person. The black figure on color is a good idea. Composition wise, it might work better if it wasn't so centered. You might enjoy reading about the Rule Of Thirds ( [link] ), a rule of composition. Another idea for compositions is that the negative spaces defined by the figure could be better if they weren't identical. And by this I mean, the left and right green surfaces are the same, and the top one has an uninteresting shape. Interesting negative spaces make for much more interesting compositions. Although many works of religious art depicting crucifixions are indeed centered compositions like yours, because centered compositions are understood as more formal and spiritual.
The glowing eyes are spooky, sure enough. As are the red lines that work as blood or veins or sculpted details within the figure. The anatomy could use some more work, although it could be judged as an example of primitivism, like Paul Gaugin tried to do ([link]). Note, however, how much more attention Gauguin for example pays to correct anatomical forms and good composition.
Overall, it is spooky, but could get spookier if you put some more thought and effort into it. See here Lilith from Neon Genesis Evangelion if you need something to aspire to: [link]
