portrait study female wip

updated a bit more, I think the eye is more correct now, still not quite right though. Still quite blotchy looking overall, thought it would look a bit smoother by now, any tips on blending?

Wip of a practice study. Trying to be careful with my measurements and more methodical with this one so I won't have to chop and re paint things half way through. I think it's going ok so far, having a lot of trouble getting that left eye, can see it looks wrong at the moment.
