quite the good one , has very much potential
if you look for advanced constructive critic , here are some points you might try again at this one to get out the maximum effect and audience impression of this :
you made some wonderful rendering at the volume of her breasts and the clothing there, but it looks illogical when you consider the shoulders. the breastmuscles connect to the armpit, and define the breast. Unless she has huge armmuscles, it doesnt make much sense.
evening light : why is it ? the sun is so much up at the horizon, unless its a different sun or atmospheric effect it is contradictive.
the folds. they are very beautiful at the arm, but they got so sloppy at the lower part , if you dont feel like it, better make it straight or more draped in one logical direction, downward
or make it a very torn end, might create some beautiful eye movement on the canvas.
here we come to the next point, eyemovement. its a beautiful idea here, but could be a bit "shorter" for the eye to travel.
ok this is an old one and you probably may noticed it yourself this time, but I feel like this should get some more deserved love
keep up the nice work man
cheers
