I see the result of a LOT of effort...
While I do admit now that my testosterone levels lead my gaze back to the center of the image, I made sure to inspect the entire work before trying to make any comment whatsoever.
First thing I did after taking a glance at the image was read the description, and it wasn't until about my fifth search that I actually found the mask you mentioned. This was a nice touch because it's a feature that isn't overbearing or painfully visible, but instead is presented in a realistic manner. (You wouldn't see much of the mask if someone had their head tilted at that angle in reality.)
Next up was the finite details in the ferns and plants gathered around her hands, and I sense from it that you have a keen eye for details. It's most impressive because it looks like a real jungle floor. From there, looking up int the background, the detail fades as if the viewpoint is focused on the seductive humanoid in front of it, and that was another impressive addition that several people seem to miss. (Or simply don't comment on.)
As per the central figure, I have to agree with Gariloce about the hair and the appearance of her being a nymph of some sort. If your instinct-driven viewer could find the willpower to look the character in the eye, the combination of her expression and the angle of her head seems to relay a very clear message:
"Follow me"
Of all this I see but one flaw; as QueenVictoria411 noted, there is an awkward discrepancy between the size of her arms. I noticed, but didn't see what threw me off at first, and looking back now, I see it: The definition of the elbow on her right arm makes it look like it's inverted (The covering of hair throws it off just enough), and then it isn't so much of a difference in size with the left arm, but that there isn't enough mass around the elbow to match the right arm.
Most impressive despite this, and sorry for giving you so much to read. I have but one question:
...Where'd she get the leather and the lip gloss? O-o
