Very well done original rendering you have done. The composition is very well placed on the canvas in an asymmetrical fashion, giving it a dynamic movement within the scale of the background and effects shown. Nice sense of form and the depiction of features, gestures and expressions are articulated nicely.
Love the combination of techniques being used here, with the soft blurs of the background adding a sense of depth and space, giving the figure placement in the world. Lighting of the form is masterfully done, with use of reflective light and foreground lighting taking the place of traditional contour lines in substance. Adding the additional blue reflective light to the floating particles is a nice touch for giving inclusion to alternate light source of the pendant....and recognizing that it is the pendant adding it, by not going overboard with the color in the background.
Only minor thing I see, and is so minor...not worth mentioning, as it does work as is in the piece...is the crow/bird used in the background. Perhaps more inclusion of it into the piece as a full form would work better, but again...having the main features provided such as the beak and talons at least give the sense of it and interest into speculating the mysteries beyond what is represented in the World as a whole.
Background itself is the only thing I would touch up on, as well as it is done to begin with. In that the colors are slightly lacking in highlighting, and become more so Opaque with the same red tone, as opposed to perhaps soft touches of a lighter tone of red, which might give the mist/swirls/busts a bit more depth.
Other than extremely minor things...of mere subjective quality, being easily forgotten...is a masterful artwork.
