Excellent work!
This is great stuff! I like the multiple tones of color on the skin and the way you lit up the scene with blue and white light. The only (picky) criticism I could find for this would be unequal level of detail when looked at full-size, for instance when comparing her eyes to the bottom of the water pillar. Then again, it's quite negligeable! I would love to see you add some grain to the skin and fabric, which I find adds a lot of realism to such renders. Keep up the great work!
