more definition on arms and body, the bottom of the robe/skirt looks kinda weird, I don't think it would fall like that. Mid belts look strange, breasts are kinda deformed.
Make it black and white and you will see the arm doesn't have much value at all, it's almost entirely the same value, needs more definition.
Face looks stretched, nose too long, chin too long, IMO. Line between eye sockets/nose is too defined, soften it up. Shading under left eye near the nose seems unrealistic.
Legs too blurry and undefined, bottom of left leg seems to blend entirely in to the stone.
Are you doing sketches to check proportions/anatomy/form/etc before hand?
