I do like the amount of shade in this piece, lots of grey in between all the black and white, tho I think it could do with some stronger white in this piece.
Pandora I am seeing a habit from you and I don't think it's for the best.
You seem to always place your focals too far to the left or right, always leaving so much empty space not played with. I would strongly suggest to use up more of the space/cut off half the dead space/ or move your focal more to center.
I also agree with the above comments, this image has too much topaz, it is very strong and makes important details look messy.
I would suggest leaving topaz out when it comes to rl images if you haven't got a good setting yet that you know how to manipulate.
i agree with slave on this totally if u use topaz i wold wait till the end when u are done and dont want to do any more stuff to the tag and dont use too much then it doesnt look like a real person anymore it will look animated like in this one
