Anemone tetrasepala from Kashmir
Beautiful upload
Seems to be Anemone tetrasepala
very nice to see this
did you also have some pictures of its surroung plants and soil etc? and lower leaves please 
Unfortunately, only a single, general image, no close-ups of flowers nor lower foliage plus no location nor altitude, making it VERY difficult
to be sure. MIGHT be what I understand to be Anemone tetrasepala.
Please be sure to take lots more images of EVERY species you photograph including close-ups of flowers (incl. under surface), plus stem and lower leaves (both surfaces).
General location and altitude REALLY are important.  
Given that there is uncertainty as to how to distinguish between some forms of A.polyanthes and some forms A.tetrasepala, having only a single image, does not help much.
